Aspectos da tecnologia em mandioca na Amazônia.
Provedor de dados: 14
Autores: ALBUQUERQUE, M. de.
A mandioca é uma cultura de extraordinária importância na Amazônia, sendo utilizada sob uma grande multiplicidade de formas, principalmente como alimento. É a cultura alimentar de maior expressão na região. Toda essa importância, no entanto, quase nenhuma influência tem exercido sobre sua tecnologia, que somente há pouco tempo começou a se modernizar em certas áreas. Nesta exposição serão abordados aspectos referentes a tecnologia atrasada de sua exploração nos meios rurais incultos e rústicos, bem como os resultados já obtidos pela pesquisa científica a qual esta afeta a substituição dessa tecnologia por outra atualizada e eficiente, capaz de alterar substancialmente as bases atuais em que se processa o cultivo e industrialização da planta. O que já foi...

Les produits naturels présentant une activité biologique et dérivés des mondes animal et végétal ont, de tout temps, reçu attention pour leur valeur bio-médicale. Dans cette démarche, qui remonte à la plus haute antiquité, l'empirisme, la constatation fortuite, la curiosité expérimentale et la systématisation du screening pharmacologique ont successivement jalonné la route du besoin, c'est-à-dire le maintien de la santé, en produisant d'abord des extraits ou isolats naturels, support des médications, puis le modèle original, point de départ à l'élaboration synthétique du composé bio-actif.

Il y était fait état en particulier du chalut de fond 27/47 et du chalut semipélagique 35/42 gréés tous les deux avec des entremises et des bras. On y traitait également du chalut pélagique à 4 faces 17,60 X 15,35 tel qu'il est utilisé par les bateaux de 150 à 200 cv, c'est-à-dire avec un gréement à fourches et des panneaux rectangulaires traînant sur le fond.

Ponte naturelle et ponte induite hormonalement chez dicentrarchus labrax L. en captivité
Provedor de dados: 5
Autores: Boulineau, F.
From the aquaculture point of view, in any interesting species, one of the first issues raised is the obtaining of some fries for rearing. The first solution is the sampling of the ovums through abdominal pressure on mature females (the well-known technique used on salmonids). However, for basses, this method provides very few advantages for too many disadvantages; the first obstacle met is the determination of the fish's exact state of maturity in order to avoid a premature or late gamete release. This implies repeated handlings, really traumatizing for this type of fish. Moreover, it is inordinately rare, if not exceptional, to come across a wild female about to lay eggs. As a conclusion, this method results in the egg laying of a large number of...

Structure et évolution des fonds océaniques. La tectonique des plaques
Provedor de dados: 5
Autores: Le Pichon, Xavier.
L'exploration de la couverture sédimentaire des fonds océaniques n'a été possible d'une manière systématique que depuis 1960, lorsque les techniques de sismique réflexion continue furent introduites pour la première fois. L'absorption du son dans les sédiments étant d'autant plus grande que la fréquence est élevée, les procédés de sondage ultra-sonore classiques qui utilisent des fréquences de l'ordre de 12 kHz ne permettent pas des pénétrations supérieures à quelques mètres à l'intérieur des sédiments meubles.  Par contre, aux fréquences de l'ordre de 100 Hz, la pénétration de l'onde sonore est beaucoup plus grande et il devient possible d'effectuer un véritable sondage continu des couches sédimentaires consolidées.

Provedor de dados: 5
Autores: Reyss, Daniel.
Genus Diastyloides Sars, 1900, is characterized by a mandible which is truncated at its base (type Leuconidae) that it is the only one to possess in the Diastylidae family. Known to this day by 5 species, its distribution area seems to be limited to the northern Atlantic Ocean, from Norway to the Mediterranean Sea. The study of the material collected during more recent cruises enabled us to extend this distribution area and lead to the description of two new species.

Evolution of Blennioidel in the Mediterranean Sea
Provedor de dados: 5
Autores: Zander, C. Dieter.
The evolution of 2 spp belonging to the gen Tripterygion and some spp of the gen Blennius is discussed. Tripterygion tripteronotus and T. xanthosoma have very similar morphological characters yet live in 2 distinct niches. This probably results from 2 separate immigrations into the Mediterranean at different eras after the glacial age. After establishing reproductive barriers these populations would have evolved into 2 distinct spp. In contrast the spp of the gen Blennius were endemic in the Mediterranean and their evolution must have taken place after the end of the glacial age. During this lapse of time, multiple differentiations which might have taken place would account for the presence of sibling spp having comparable morphological characters but...

From two series of specimens of the genus Heterospio (Polychaetous Annelids, sedentaria) collected in the western Mediterranean,  the authors describe two new species : the first one (H. mediterranena sp. n.) lives in bathyal muds, the second one ( H . reducta sp. n.) inhabits the abyssal plain.  The two new species are compared with the two (or three) other species previously known. These samples corroborate the recent discovery of a single specimen of this rare genus in the Mediterranean.

Autores: Alliot, A.; Febvre, A.; Marquet, R.; Metailler, R.; Pastoureaud, A.
The experimental study of marine animal nutrition raises a number of technical issues, especially that of food distribution, when it is supplied in the form of pellets with a low water content. Hand feeding has different disadvantages. Farmers have indeed to supply an increasing number (for experimental purposes) of batches, several times per day and at regular intervals, with various types of food of well-defined quantities. Thus, many hours are dedicated each day to feeding. Moreover, the large number of interventions implied influences the fishes' behaviour.

Le problème de l'existence d'une véritable faune abyssale en Méditerranée est depuis longtemps posé et n'est pas encore résolu. On admet généralement qu'en raison de la structure homothermique des eaux profondes méditerranéennes, la plaine abyssale est peuplée par des espèces bathyales eurybathiques sténothermes chaudes, Mais, comme le souligne PÉRÈS [1967, p. 467] l'extrême pauvreté des grandes profondeurs méditerranéennes et le nombre très limité de prélèvements faits à ce jour ne permettent guère de donner une réponse satisfaisante à cette question.

La récolte mécanisée des laminaires - Ses conséquences sur les peuplements
Provedor de dados: 5
Autores: Perez, René.
En 1969, un groupe d'ingénieurs goémoniers a mis au point un nouvel outil pour la récolte des laminaires. L'appareil se compose d'une longue tige métallique portant une barre semi-circulaire soudée à son extrémité basale. Lorsque de la barque on fait tourner cet outil en le tenant verticalement, la barre semi-circulaire oblige l'algue à s'enrouler autour de l'axe jusqu'à ce que le crampon se détache. Il ne reste plus alors qu'à remonter l'appareil et à dénouer la fronde étroitement enlacée sur la tige métallique. Les thalles étant généralement disposés par groupes, c'est l'ensemble qui s'enroule autour de ce que l'on a communément nommé "scoubidou".

Growth inhibition was tested using Phaeodactylum tricornutum and Gyrosigma spencer (algae). To 0.5 ml of culture inoculum containing similar to 100000 cells in exponential growth phase, 9.5 ml of insecticide in varying concentrations were added and the growth was recorded every 48 hour; LG sub(50) was determined. Muscular activity and filtration rate of Crassostrea angulata were tested. The acute toxicity was tested using 4 species of gastropods, 2 lamellibranchs, 5 crustaceans, 1 coelenterate and 3 fishes; the species used were: Gibbula umbilicalis, Purpura lapillus, Littorina littorea, Patella vulgata, Mytilus edulis, Cardium edule, Artemia...

Autores: Laubier, Lucien.
A new form of Annelida Polychaeta sedentaria has been collected in the eastern Mediterranean, at depths greater than 3 000 m, on the eastern limb of the Matapan trench. Its study leads to the proposition of the creation of a new genus of Ampharetidae. Some characters specific to this genus drove us to consider the definition of a new family. Given the current state of our knowledge, it seems sensible to consider Uschakovius gen. n. as an aberrant genus of Ampharetidae.

The advertising effort developed by the Japanese National Fisheries Agency (Research department) for the spreading of statistical data on tuna longline catches and effort is, at first, a surprising subject in the eye of professionals and scientists. Two reasons can be cited as an explanation: On the one hand, the maximum precision of the data (date, location, amount of catches) and, on the other hand, the short period of time between the fishery and the publication of the obtained results in the form of a very precise annual report. This publication without distrust is currently the demonstration of what scientists have been pleading to professionals for half a century: the success of a nation, of a state, of a fleet in the exploitation of the ocean's...

Sampling was carried out during 1970 at 22 stations from 72 degree -62 degree N; the sampling period varied from 21 minutes - 42minutes. 12 species of zooplankton were recovered consisting of specimens of copepods, euphausiids, chaetognathes, medusae, amphipods, pteropods and decapods. They were most abundant in the central zone, especially in 2 areas of maximum concentration (where the catch exceeded 100 cm super(3)) located 72 degree N and 67 degree N. Fish captured included young cod, rockfish and halibut; they were found mostly around these areas of maximum zooplankton concentrations. Only immature fish were recovered in this region; the adults had deserted these waters due to unusual and permanent low temperature water in the superficial layers.

The use of the Rotifer Brachionus plicatilis has spread for a few years in the laboratories dealing with the rearing of marine fish larvae. Thanks to the works by Theilacker and Mac Master (1971) in the U.S.A., and by Hirayama and Ogawa (1972) and Hirayama and Kusano (1972) in Japan, the conditions to follow to rear large quantities are well-known. The common method used consists of placing a Rotifer inoculum in a mono or plurispecific culture of planktonic algae ("green water"), in leaving them to multiply exponentially at the expense of the alga, and to use them before they run out of food.

L'exploitation de la coquille Saint-Jacques au Japon
Provedor de dados: 5
Autores: Muller-feuga, A; Querellou, J.
King scallop, Patinopecten yessoensis (Jay), is one of the cold water species whose exploitation is the oldest in Japanese waters. In the bay of Mutsu, its fishing intensified in the middle of the Tokugawa era (1615-1868) and scallops held an important place in the trade with China. At the beginning of the Meiji era, king scallop was mostly fished in Hokkaido, in the bay of Funka and on the south-west coast of this island. Around year 25 of the Meiji era (1893), it spread to the coasts of the Okhotsk Sea. This exploitation provided a production which varied considerably from one year to the other, but was a central element of the activity and economy of fishing villages.

Les poissons de la famille Echeneididae (Remoras) de la Mer Ligure et de la Mer Tyrrhenienne
Provedor de dados: 5
Autores: Tortonese, E.
Five spp of Echeneididae are presently known in the Mediterranean: Echeneis naucrates L., Remora remora (L.), R. brachyptera (Lowe), R. australis (Benn) and Rhombochirus osteochir (Cuv). All of them may now be reported from the area comprising the Ligurian and the Tyrrhenian seas. Many mistakes occurred in the past, chiefly concerning R. remora a name too often wrongly applied to different spp. Echeneis holbrooki from the gulf of Genoa is really E. naucrates. Only 2 specimens of R. brachyptera were found, both in Sicilian waters. R. australis is here recorded from the Tyrrhenian sea. Rh. osteochir has been hitherto overlooked, but probably is the commonest Echeneid in the Mediterranean. A list is given of specimens from several localities (Gulf of Genoa,...

Provedor de dados: 5
Autores: Choukroune, Pierre; Le Pichon, Xavier; Seguret, Michel; Sibuet, Jean-claude.
The different hypotheses proposed for the creation of the Bay of Biscay are reviewed. New geological and geophysical data collected in the last two years in the Bay and in the Pyrenean domain give new insight into the tectogenesis of the Pyrenees.  Geological data of the Pyrenean area provide tight constraints on the hypothesis of formation of the Bay. The most probable hypothesis is an opening by rotation of the Iberian Peninsula around a pole of rotation situated near Paris, which resulted in strike-slip motion dong the North Pyrenean fault during the Upper Mesozoic.  A progressive westward migration of the pole initiated in the late Cretaceous blocked the motion dong the fault and led to the main Eocene tectogenetic Pyrenean phase. [NOT CONTROLLED OCR]

Autores: Cavanie, Alain.
Différents écoulements océanographiques, météorologiques ou industriels peuvent être décrits par des modèles théoriques ou expérimentaux formés de deux couches fluides superposées.  Dans les cas où l'hypothèse des ondes longues est justifiée (hypothèse de pression hydrostatique), ces écoulements sont décrits par un système hyperbolique d'équations aux dérivées partielles non linéaires,  sous réserve que les grandeurs caractérisant les écoulements ainsi que leurs dérivées premières satisfassent à un certain nombre de conditions de continuité.  De même que pour les écoulements de surface où de la dynamique des gaz, il est intéressant d'étudier les relations qui relient de part et d'autre des surfaces de discontinuités,  les grandeurs physiques qui...

Résultats préliminaires de l'expérience de collecte de naissain de coquille saint-jacques en rade de brest et baie de saint-brieuc
Provedor de dados: 5
Autores: Buestel, Dominique; Dao, Jean-claude; Muller-feuga, A.
King scallop production in Japan enjoys a wonderful evolution one would like to find in other exploited marine species. In the Bay of Mutsu, one of the main exploitation centres, the production went from 430 t in 1963 to 6 000 t in 1969 and to about 40 000 t in 1972. Responsible for this development is an original method of spat collection, supplying the suspended cultures and the seabed seedings: the animal biology is taken into account. During its juvenile stages, it looks for a substrate for its metamorphosis, gets a hold of it thanks to a byssus, and stays for a few months before developing its benthic animal behaviour. The trick is to provide the scallop with a support, isolated in a fine mesh bag through which larvae can go but where the young shell...

Contribution scientifique a la grande pêche campagne du « Cryos » de janvier à Mars 1973 dans le golfe du Saint-Laurent et sur les bancs méridionaux de Terre-Neuve

This cruise of the "Cryos» enabled us, based on our observations on the biology of the cod stocks, the thermic environment and the catches, to explain the situation of the fishery in the gulf of the Saint-Laurent and on the southern banks of Newfoundland, from January to March 1973. Our best catches were made in the Banquereau area and especially in the gulf of the Saint-Laurent. Unfortunately, the fleet of the Grande Pêche has not cruised much around the Banquereau area in the past years, and the very low quotas set in June 1972 by the ICNAF (International Commission of the North-Western Atlantic Fisheries) in this area (4 Vs) do not allow any further development. On the contrary, the catches of the metropolitan trawlers in the gulf of the Saint-Laurent,...

Role de Sprattus sprattus (Linne, 1758) dans l'utilisation du zooplancton des eaux Roumaines de la Mer Noire
Provedor de dados: 5
Autores: Porumb, Loan I.
Feeding of the S. sprattus was studied comparatively with the dynamics of the zooplanktonic trophic base. In April, the sprat consumed 1,459 t of zooplankton, especially Acartia clausi (84 per cent). Zooplanktonic productivity was 30 per cent due to Acartia clausi, and the sprat consumed 56 per cent of this copepod production. In April, the wt growth of the sprat was 115 t. In May, the sprat consumed 6.201 t of zooplankton, that resulted in a fish production of 492 t. A clausi contributed 36.41 per cent to the zooplankton production and the sprat fed on copepods at a level of 93 per cent. In June, only 1,094 t of zooplankton resulted in a fish production of 87 t. Zooplanktonic production was 60 per cent due to A. clausi, and only 12 per cent of this was...

Magnetic anomaly pattern in the western mediterranean
Provedor de dados: 5
Autores: Bayer, R.; Le Mouel, J.l.; Le Pichon, Xavier.
A survey of the southern part of the Balearic Basin was flown in 1971 at a height of 600 m. The results of a survey of the northern part, flown at a height of 3000 m, which was previously published, have been downward continued to a height of 600 m. The resulting composite map shows well defined low amplitude (100 gammas) magnetic lineations of the Vine et Matthews' type offset by fracture zones. The lineated zones are bounded by large quasi-circular anomalies on the edge of possibly "continental" non magnetic zones. The results define a complex kinematic pattern of the opening of the Balearic Basin, in terms of plate tectonics. [NOT CONTROLLED OCR]

New high-energy implosion seismic source
Provedor de dados: 5
Autores: Avedik, Felix; Combe, Robert.
Elimination of bubble pulses has been the main concern of air gun users for the past years. Until now, the proposed solutions: divided chambers, spheres, have resulted in an appreciable loss of acoustic energy. The Casios-Simplon Water Gun, developed by CNEXO and SODERA, solved this problem using surprisingly simple means, which not only eliminate the disturbing secondary effects (bubbles) but greatly increase the acoustic efficiency of the air gun. The system uses the air gun as a pneumatic accelerator and creates the acoustic pulse by implosion. The emitted signal is free of disturbing secondary effects and its power spectrum closely approaches the spectrum of dynamite type sources. [NOT CONTROLLED OCR]

Estimation de la mortalite totale du Merlu

Autores: Guichet, Roger.
In this paper the instantaneous total mortality coefficient for hake is estimated., using c.p.u.e. data of La Rochelle deep-sea trawlers from 1968 to 1970. The following two methods are used to calculate the mortality coefficient Z: the first one is obtained with the c·.p.u.e. of two successive year classes for the same year, the second is estimated with the c.p.u.e. of one year class taken in two years rurming. Everywhere, except for the West Ireland area, the total mortality seems to decrease with the age of the fish. Such a result was not observed with the "Thalassa" experimental data in the Bay of Biscay. This suggests a change in fish catchability with age. Generally, there is no great difference between the results of the. two methods. Nevertheless...

This study concerns mainly 2 species Merluccius capensis and M. paradoxus; M. polli is a more northern species though the 3 species are known to inhabit the same regions. The life cycle, seasonal migrations geographical distribution and fishing grounds of the 2 main species are discussed in detail. The intensity of fishing in this region, over the past 10 years has increased to such an extent that during 1968 -1970 this production accounted for one half level on a world-wide basis. Attempts have been made by Britain to market this fish as a frozen product.

The word "Krill" has been used, then largely adopted, to designate the enormous concentrations of Euphausiacea Euphausia superba in the Antarctic Oceanic areas which represent the largest part of whales' diet. From a scientific, taxonomic and biological point of view, this word "Krill" can be applied without any restriction to the summer concentrations of Euphausiacea appearing in July off the Cap Finisterre and named "Rouges de crevettes" (shrimps' reds) by albacore fishermen. The only difference is that these superficial concentrations are almost exclusively made up of another species of Euphausiacea, largely widespread in the whole North Atlantic Ocean: Meganyctiphanes norvegica whose size does not exceed three centimetres.

Provedor de dados: 5
Autores: Yannopoulos, A; Yannopoulosa, C; Soteriades-vlahos, C.
The spawning and nursery grounds of 3 spp of commercial importance, Engraulis encrasicholus, Sardinella aurita and S. pilchardus were studied in the Saronikos Gulf during 1969, 1970 and 1971. The waters of the gulf are very rich due to turbulence caused by currents penetrating the gulf from the Aegean Sea. This turbulence causes bottom upwelling especially in the northern region which is shallower. At the height of their reproduction these fish represent 90-95 per cent of the entire ichthyoplankton, especially in the northern region. E. encrasicholus appears to be the most abundant sp with a maximum of 1099/m super(2) of surface waters (where the density of eggs = 536 and of larvae = 563). 232/m super(2) of surface water represents the maximum for S....

The results of this first trial show that trout culture in sea water is possible in a carefully chosen site. It seems necessary to have both a water with an average salinity and a good quality fresh water, the latter being used to adjust the salinity rate to the needed value during the adaptation period and stabilize the temperature in case of important heat. Moreover, fresh water must be used as a dissolved oxygen source when this element is not found in sufficient quantities in sea water. Despite the relatively precarious conditions in which this experiment was conducted, about seven tonnes of " sea trout" have been produced from an initial input of one and a half tonnes. These large Salmonids show a white silvery look (fig. 13). Most dots have...

As a result of 5 years of sampling the following results were reached: (1) so far as growth was concerned 3 size groups were recognised during June-July. The `classic' type measuring similar to 52-62 cm, a group ranging from 54-55 cm and a 3rd group measuring 64-65cm. By marking the fish and by studying the degree of distribution of the stomach parasite, H.fusca it was noted that the albacore entering the north east Atlantic during summer constitute a heterogenous population migrate along the same route upto the north west boundary of Cape Finisterre. Thereafter they diverge, one group forming a semi-circle along the Bay of Biscay, another moving northwards and on reaching the south of Ireland bends westward.

Perspectives ouvertes par les données récentes sur l'endrocrinologie de la reproduction des poissons, pour le contrôle de leur cycle reproducteur
Provedor de dados: 5
Autores: Breton, B.; Billard, R.
The use of hormonal factors in the induction of artificial egg laying was introduced in fish farming following the first works by Houssay in 1929. Since then, this technique has not evolved much. Pickford and Atz in 1957 have reviewed, exhaustively, most of the attempts carried out to date. This approach is still widely used, and in this way numerous hormonal concoctions have been put into use: mammalian hormones LH, FSH, HCG, PMS... and some fish hypophyseal extracts (mostly carp) often in a raw state. The hypophysation technique can be considered as finalized in the carp, through the use of homologous concoctions. However, in other species, success is more unpredictable and variable, depending on the nature of the hormones used.

Before I get to the heart of the matter, I would like to precise the main objectives of this cruise as well as the conditions in which it took place. A year earlier, we had managed to obtain for the first time 12 000 Atlantic wolffish fries from farmed spawners. Therefore we had to demonstrate that these experiments were repeatable and that they could be adapted to a mass production leading to the rearing of 30 000 to 50 000 fries. These are the terms of the collaboration contract between the C.N.E.X.O. and the Sete Station.

Régime alimentaire et pourcentage de survie chez la larve de sole (solea solea l.)
Provedor de dados: 5
Autores: Girin, Michel.
The first metamorphoses during rearing of flounder larvae were obtained at the beginning of the century, in France, by Fabre-Domergue and Bietrix (1905). Sixty years later, their experiments were taken over by Fluchter (1965-1972) in Germany, and Shelbourne (1968) in Great-Britain. The first one focused on the laboratory study of the impact of the water quality on the rearing success, and the latter, on the development of industrial hatcheries. Both obtained metamorphosis with survival rates varying from one egg laying to the other and reaching 80 % in the best batches. They explain these variations through genetic differences or pathological phenomena.

Heteropoda
Provedor de dados: 5
Autores: Thiriot-quievreux, Catherine.
The heteropods are transparent planktonic animals, whose systematic position has undergone considerable reappraisal since the last century.  It was Lamarck who, in 1812, created the order Heteropoda, which he placed between the Cephalopoda and the fishes, and brought together the genera Carinaria, Firola and Phyllirhoë.  Later, Cuvier (1829) added to these the genus Atlanta. [NOT CONTROLLED OCR]

Développement larvaire de mytilus edulis(L.) en présence d'antibiotiques
Provedor de dados: 5
Autores: Le Pennec, M.; Prieur, D.; Chardy, P.
The influence of different concentrations of four antibiotics : chloramphenicol, aureomycin, erythromycin and sulfamerazin, on the larval growth of Mytilus edulis (reared in the laboratory from the straight hinge stage on to metamorphosis) has been studied by an analytic method. The growth at once is a function of the antibiotic utilised and of its concentration in the culture vessel. The growth is rapid with erythromycin and chloramphenicol and slow with aureomycin. It is more important when the concentration of chloramphenicol increases. It is the contrary with aureomycin and erythromycin. [NOT CONTROLLED OCR]

Inventaire des différents types de cages à poissons
Provedor de dados: 5
Autores: Virmaux, J.f.
L'aquaculture, quelque soit son stade ou sa forme, ne peut se concevoir sans le concept d'enclos.  Au stade de l'écloserie, on parlera de bacs, à celui du grossissement, d'enclos en élevage extensif et de bassins et cages en élevage intensif.  Dans ce dernier type d'élevage, les cages à poissons semblent être, à l'heure actuelle, promues à un riche avenir, et à cela plusieurs raisons: leur facilité d'implantation, leur souplesse d'exploitation, leur investissement et leur frais d'exploitation sensiblement réduits comparés à ceux des bassins. Les cages à poissons ont déjà fait leurs preuves, tant du point de vue technique qu'économique dans certains pays comme le Japon, la Norvège, les U.S.A., et en sont encore au stade expérimental chez de nombreux autres....

Les pêches maritimes sur les cotes françaises de méditerranée - Actualité, perspectives
Provedor de dados: 5
Autores: Bonnet, Marc.
From a geographic point of view and its impact on marine fisheries, two different aspects of the French Mediterranean coast can be considered:- west of Marseille, the coasts are low, sandy, with a regular outline, and slowly go down into the sea where they form a continental platform whose surface is exceptional for the Mediterranean Sea; it is the Gulf of Lion and the numerous lagoons which surround it; - east of Marseille, the coasts are rocky, craggy, very irregular and overhang a similarly uneven seabed; they are the coasts of Provence and Corsica. Furthermore, the waters of the Gulf of Lion, contrary to those of the eastern coasts benefit from some important fluvial inputs, from the Rhône River for most of them, which favour their productivity.

La diatomee Navicula ostrearia Bory en baie de Bourgneuf
Provedor de dados: 5
Autores: Robert, Jean-michel.
Previously, Navicula ostrearia B. has been described only from the  Marennes-Oleron district of the Atlantic coast of France. However, this pennate diatom is also present In the Bay of Bourgneuf where breeding of green-gilled oysters were recognized in sea basins called oyster ponds. A short description of observations made with the optical microscope precedes description of high magnification examination of the frustule made with the scanning electron microscope. This combination of techniques shows a polymorphism between the external and internal surfaces of diatom valves.

Le problème de la disparition des herbiers à Posidonies dans le golfe de Giens (Var)
Provedor de dados: 5
Autores: Maggi, Pierre.
The issue of seabed destruction in the Gulf of Giens, is certainly linked to a regression of Posidonia oceanica which does not carry out its protecting role towards loose substrates. These destructions lead, through the creation of a new balance profile, to irreversible beach deterioration processes. The disappearance of seagrass seems linked not only to the quantity but also to the quality of the urban waste flowing into the gulf. The issue of seabed destruction in the Gulf of Giens could be solved in a favourable way for the marine fauna and flora by stopping the waste input in this environment and rejecting them south of the peninsula at depths of 40 to 50 m where strong currents enable a good thinning of the effluents. After the pollution issue is...

Autores: Furnestin, Marie-louise.
56 samples were collected from 14 stations along the Spanish coast, the North African coast, the Balearic Islands and Sardinia. 60 species of diatoms were recorded made up mostly of tychopelagic and benthic forms; these were far more abundant than the Dinophyceae of which only 22 species were recorded. 6 species of phytoplankton were dominant and represented similar to 70% of the total samples. The average content of chlorophyll a at depths of 1-70 m was 0.35 mg /m super(3), that of chlorophyll b was 0.15 mg/m super(3) and that of chlorophyll c was 2.20 m-S.P.U./M super(3)/hour. The highest level of chlorophyll a corresponded to regions of very low phosphate levels and the number of cells and species were at a maximum for an incident light of 10-15% and at...

The origin of the western Mediterranean basin
Provedor de dados: 5
Autores: Auzende, Jean-marie; Bonnin, Jean; Olivet, Jean-louis.
The evolution of the western Mediterranean basin is considered. The Provence basin results from the Oligocene migration of Corsica and Sardinia southeastwards. The North African basin was created by the dislocation of an 'internal zone plate' by the mechanism invoked by Karig. Lower or middle Miocene squeezing of the internal zones against the North African platform caused ejection of the flysch nappes. [NOT CONTROLLED OCR]

Nocivite relative de cinq detergents anioniques en milieu marin. 2. Relation entre la biodegradation et la toxicite aigue
Provedor de dados: 5
Autores: Cossa, Daniel; Maggi, Pierre.
In this research, biodegradation associated with evaluation of the variations of acute toxicity of 5 anionic detergents towards Anguilla anguilla is described. It appears that the process of anionic detergent biodegradation in sea water is similar to the results obtained by many authors working on fresh water. The experimentation shows 2 different kinds of behavior among the 5 anionic detergents tested: (a) the first category is composed of syndets, without aryl group in their formulation, which are promptly oxidized by bacteria and do not reveal variation of acute toxicity during their biodegradation; (b) the other group includes LAS; those syndets need a quite long bacterial acclimation. On the other hand, their toxicity is reduced whilst they are...

Autores: Alliot, E.; Febvre, A.; Metailler, R.; Pastoureaud, A.
Le Bar, appelé Loup en Méditerranée, est un poisson téléostéen très apprécié et recherché sur le marché ; sa pêche est relativement peu abondante et l'élevage d'une telle espèce paraît prometteuse. L'acclimatation en bacs et l'adaptation aux conditions d'élevage sont facilement réalisables. D'autre part, la reproduction contrôlée de cet animal peut être considérée comme pratiquement dominée. Il devient donc urgent d'approfondir nos connaissances sur ce poisson, surtout quant à ses besoins nutritifs, pour obtenir une croissance rapide en élevage.

La maladie de la glande digestive d'Ostrea edulis Linne
Provedor de dados: 5
Autores: Grizel, Henri; Tige, Gilbert.
The first microscope observations of the digestive gland of Ostrea edulis were conducted by Comps (1970) and Herbach (1971), but the first effects had already been observed in the autumn of 1967. During summer 1968, an abnormal mortality occurred in the upstream part of the Aber Wrach, then spread downstream and into the Aber Benoît. Similar mortalities were also observed in the area of La Tremblade and in the Arcachon Bay. Since then, a permanent monitoring is conducted in the different Breton oyster culture centres and the Arcachon area.

Autores: Delor, Anne.
Willing to acquire the fish culture techniques necessary to tackle the issues raised by marine fish culture, we undertook training in the U.S.A. and chose as our research subject the American Striped Bass (Roccus saxatilis WALB, 1972) whose semi-intensive culture is booming (l). To start with, we will recall some biological data. It is a Perciforme belonging to the Serranidae family, abounding on the Atlantic coast of the United-States. It is found all the way from Canada to the North of Florida, which shows a great eurythermy. Moreover, it is an extremely euryhalin fish: it lives either in the ocean, along the coasts, or in brackish waters, in bays and estuaries, and can swim upstream to areas where salinity is almost null. Adult individuals of the same...

Tentative de contrôle expérimental du sexe chez la truite arc-en-ciel : production d'animaux stériles et d'hermaphrodites simultnés autofécondables
Provedor de dados: 5
Autores: Billard, R.; Chevassus, B.; Jalabert, B.; Escaffre, Anne-marie; Carpentier, M.
In some gonochoristic Teleosts, the sexual phenotype seems likely to be inverted in relation to the genotype, in some specific experimental conditions (cf. review by T. Yamamoto, 1969). Up to now, the best way to obtain such a result has been the administration of exogenous steroid sexual hormones in the fries' diet, before the normal gonad differentiation period. This way, T. Yamamoto (1953, 1958) obtained some total sexual inversions for the first time, either in the male direction, or in the female one, through the action of methyltestosterone and estrone in the Medaka (Japanese Killifish) Oryzias Latipes, then in the goldfish Carassius auratus (T. Yamamoto and T. Kajishima, 1968).

L'élevage de la sériole au Japon

Cette pêche est encore actuellement une des plus importantes activités côtières. L'abondance de Seriola quinqueradiata sur les côtes japonaises, sa croissance très rapide et les facilités d'approvisionnement en jeunes, prédisposaient cette espèce à l' élevage, qui fit son apparition il y a quelques dizaines d'années et se développa rapidement à partir de 1957.

Observations océanographiques dans le détroit de Gibraltar pendant la campagne Phygib (septembre - octobre 1971)
Provedor de dados: 5
Autores: Cavanie, Alain.
The Gibraltar straight, the only communication area between the Mediterranean Sea and the World Ocean is an area of great interest for oceanographers. It is well known that, in the straight, water flows in two overlaying layers. The Atlantic water upper layer flows into the Mediterranean Sea to compensate for evaporation loss and in the lower layer, the Mediterranean water, more salted and denser, outflows into the Atlantic Ocean. These two opposite flows maintain the level of water of the Mediterranean Sea and its salinity. The measurements made in the straight over the last fifteen years demonstrated the presence of internal waves propagating at the interface of these two water layers and generated by the periodic tide currents at the threshold of the...

Structure et évolution tectonique du bassin d'Alboran
Provedor de dados: 5
Autores: Olivet, Jean-louis; Auzende, Jean-marie; Bonnin, Jean.
The Alboran Sea is made up of two distinct basins. The first one has approximately the shape of a lozenge, surrounded by the arc of Gibraltar and the two thresholds (northern and southern) of Alboran. It is about a hundred kilometres at its largest width. Its average depth is only 1 300 m, that is 1 000 m less than in the Algero-balearic and Provencal basins. The second one is elongated, deeper (1 800 to 2 000 m) and is widely open to the east and northeast on the algero-balearic basin. The route to this latter basin is made through a more marked slope of a gradient of around 500 m and oriented NNE-SSW.

CNEXO - Rapport annuel 1973
Provedor de dados: 5
The year of 1973 was mostly the year of the dislocation of world markets, raw materials and energy materials. If it had been possible to foresee and carry out the preparation and exploitation of oceanic resources according to gradual investments and technical solutions enabling the acquisition of oceanic products at a price set by a pretty stable market, 1973 can be considered as a year of rupture. From now on, a marine raw material or energy material can become quasi-immediately indispensable, no matter its price or its exploitation technicality, because of the fluctuations of the global supplying policies. It can also be considered that, given the extent of the evolution of raw material and energy material prices, some marine deposits, without any...

Morphology, limits, origin, and age of salt layer along south atlantic african margin
Provedor de dados: 5
Autores: Pautot, Guy; Renard, Vincent; Daniel, Jacques; Dupont, Jacques.
The west African continental margin between Abidjan (Ivory Coast) and Walvis Boy (Southwcst Africa) was surveyed in 1971 by the R/V Jean Charcot.  Fiftyeight seismic-reflection (flexotir source), bathymetric (3.5 and 12 kc), gravimetric, and magnetic profiles were obtained. The seaward limit of an evaporitic zone outlined during the survey is at the boundary between continental slope and continental rise.  Variation of depth of this limit as a function of latitude shows the presence of a large offset at 11°S which seems to be related to an east-east-southeast line of magnetic seamounts cutting into the continental slope.  The Annobon-Cameroun volcanic axis separates the salt zones of the Nigerian basin and Congo-Angola basin.  The northern limit of Salt...

Autores: L'Herroux, Michel.
The use, as an aquaculture technique, of the double bottom supporting a sediment layer has numerous advantages. As far as the sediment is concerned (essential in the case of the Penaeid shrimp), this technique alone allows the sediment to stay clean as it is constantly oxidized through the percolation it creates. The water running through the sediment can either be drained off or recycled: - It has to be drained off in the case of heavy loads as it may contain some toxic products, incompletely decomposed by the bacterial activity, and especially some unsaturated short chain hydrocarbon (hexenes for most of them). - Otherwise, it can be recycled, through the use of an "Air-lift" system allowing its oxygenation at the same time. In this case, and if the set...

The current repopulation trials of the lobster beds of the Armorican continental shelf and especially those of the Belle-Ile, Houat and Hoedic archipelago provide an opportunity to study objectively this new trend: "repopulation experiment". This opportunity was seized in 1973 and materialized by the beginning of a collaboration between the CNEXO and the UNICOMA on the objective assessment, through a scientific analysis of the possible impact, of the repopulation of the lobster beds exploited by the fishermen belonging to the Groupement des Pêcheurs Artisans d'Houat (GPAH) (Houat fishers...

Teneur en mercure dans les moules du littoral français
Provedor de dados: 5
Autores: Thibaud, Yves.
Our results show that the contamination of the French coasts by mercury is quite low, and that if there is a greater contamination, it is extremely localized. In this way, in the roadsted of Toulon, where numerous samplings have been conducted, cultivated mussels are barely contaminated whereas those which grow a few kilometres away, on the docks of the arsenal show high concentrations, due to waste from the workshops. A sample collected on an old ship hull showed a content close to 5 mg/kg; the reason for this high content is most probably the presence of mercury salts used as an antifouling agent in the painting of the hull. Therefore, it seems that the risk of mercury contamination is very low apart from the fauna living in the polluted parts of the...

Autores: Comps, Michel; Gras, Paul.
A year after the end of the Gill disease which heavily struck the Portuguese oysters Cassostrea angulata Lmk. (Marteil, 1968), a new disease whose causes are still unexplained caused a massive mortality in the same species in the summer of 1970 (Comps, 1972). It can be considered, in 1973, that the successive losses lead to the quasi-extinction of the species C. angulata in the farms of the Marennes basin, since, contrary to what has been done in the case of the Malpèque disease in Canada, the indigenous specious was replaced by another species, the Pacific oyster Crassostrea gigas Thunberg.

Autores: Delor, Anne.
Being familiar with the different fish culture techniques, we tackled the issue linked to the biology of the Striped bass as they were appearing. This way, we tried to answer the questions raised by the incubation of semi-pelagic eggs, the nutrition of larvae, their conditioning and the role played by a number of physical factors on the hatching and larval survival.

Autores: Comps, Michel; Razet, Daniel; Quiroz-ramos, Hernando.
Following the "gill disease" of the Portuguese oyster (Crassostrea angulata LMK.) and the massive mortality rates that this species suffered in 1970 and 1971, the oyster farmers of the Marennes-Oléron basin, as those in other Portuguese oyster-producing areas, developed Pacific oyster (Crassostrea gigas) cultivation in France by directly importing spat from Japan's main supply centres.

Popping rocks and lava tubes from the Mid-Atlantic rift valley at 36° N
Provedor de dados: 5
Autores: Hekinian, Roger; Chaigneau, M.; Cheminee, J.l.
During the 1972 Midlante* cruise of the RV Jean Charcot to survey a limited area of the rift valley south of the Azores, a dredge (CH-DR11) was taken at a depth of 1,360 fathoms in a depression near the foot of the eastern wall at latitude 36° 49.3' N and longitude 33° 15' W.  Two types of rocks were recognized from their structure and their degree of weathering. One type is "slab-like" rock, 2 to 13 cm in diameter and 1 to 2 cm thick (Fig. la and b).  The other type of rock consists of oval glassy pebbles (1 to 5 cm in diameter, Fig. 1c) which were observed to jump and explode, one or two at a time, for 3 d after the dredge haul was emptied on to the deck of the ship.

Diapiric structures off niger delta
Provedor de dados: 5
Autores: Mascle, Jean; Bornhold, Brian D.; Renard, Vincent.
Several marine geophysical profiles off the southern part of the Niger delta reveal the presence of diapiric structures beneath the continental slope and rise. The origin of the diapiric material appears to be deep in the sedimentary section and is believed to be of Aptian-Albian age. If this hypothesis is correct, the presence of evaporite basins, known between angola and Gabon, can be extended as far north as the Niger delta. [NOT CONTROLLED OCR]

Les Cephalopodes recoltes en Mediterranee par le 'Jean-Charcot'. Campagnes Polymede 1 et 2
Provedor de dados: 5
Autores: Mangold-wirz, Katharina.
Eleven spp of cephalopod were collected with the Isaacs Kidd midwater trawl during the Polymede expeditions on the N.O. 'Jean Charcot' in the western Mediterranean and in the vicinity of Cap Finisterre. The most abundant sp was Histioteuthis reversa. 14 spp were collected with the bottom trawl Marinovitch in the western part of the Alboran Sea. The most abundant mesobenthic sp was Bathypolypus sponsalis. The specimens, very similar to the type specimen from the Atlantic, are very different from the animals captured in the Catalonian Sea.

In Japan, during the five first years, some penaeid shrimp farms have been frequently and heavily damaged by some bacteria and fungi attacks. Until now, these bacterial diseases affecting wild and cultivated crustaceans were only limited, for the most part, to the lobster disease (Gaffkemia) caused by the micrococcus Gaffkya homari (Hitchener and Snieszko, 1947), and to the exoskeleton diseases (Shell disease or Brown spots disease) caused by chitino destructor bacilluses and observed in different crabs (Gordon, 1966; Rosen, 1967), in the lobster (Hess, 1937) and in the shrimp Palaemon serratus (Anderson and Conroy, 1968).

Résultats biologiques de la campagne Polymède IV. - Micronecton en Méditerranée occidentale et proche Atlantique : données quantitatives et comparaisons
Provedor de dados: 5
Autores: Le Gall, Jean-yves; L'Herroux, Michel.
The authors study and compare the biovolumes of 69 samples collected with an Isaacs-Kidd trawl during the Polymède cruise of the R.V. Jean Charcot (May and June 1970) in the eastern Mediterranean Sea and around the Cap Finisterre. Based on these quantitative bases, along the 5° East meridian, two basins can be distinguished in the eastern Mediterranean Sea: - one located north of the Balearic insular arc, - the other located south of the same arc. The comparison between these two basins shows a greater "richness" of the northern area. This is especially remarkable for Euphausiacea (ratio of 1 to 30). At this time of the year and at this trophic level, no specific influence of the North-African Atlantic current can be found. A similar sample collection off...

Evolution et conséquences de la mortalité de C. angulata dans le bassin d'Arcachon et l'estuaire de la Gironde de 1971 à 1973
Provedor de dados: 5
Autores: Deltreil, Jean-pierre.
A peine l'ostréiculture se relevait-elle des dommages causés en 1967-1968 par ce qu'on a appelé la "maladie des branchies" qu'une deuxième épizootie décimait en 1971 les populations de C. angulata sur l'ensemble du littoral français. Cette situation rappelle celle qu'avait connue O. edulis vers 1920 dont la mortalité avait favorisé l'extension de C. angulata; cinquante ans plus tard, l'ostréiculture a du s'orienter rapidement vers une autre espèce, C. gigas. Nous décrivons l'allure des phénomènes de mortalité et les conséquences qui en ont résulté dans les régions ostréicoles du bassin d'Arcachon et de l'estuaire de la Gironde.

Biologie et pêche du céteau (Dicologoglossa cuneata Moreau) dans le sud du golfe de Gascogne
Provedor de dados: 5
Autores: Forest, Andre.
Le céteau, Dicologoglossa cuneata (Moreau), est pour les pêches françaises en Atlantique, une espèce d'importance économique très secondaire : il n'apparaît pas dans les statistiques de la Marine Marchande et l'on peut estimer sa production aux environs de 450 ou 500 t par an. Il fait néanmoins l'objet d'une pêche particulière de la part de bon nombre de chalutiers artisans des Sables d'Olonne, de l'Ile d'Yeu, de La Rochelle, de l'Ile d'Oléron et d'Arcachon.

During the Polymede II cruise conducted by the R.S. "Jean-Charcot" and organized by the Scientifc department of the C.O.B., two sectors of the Ionian Sea have been the focus of a biological study of the benthic populations: the abyssal plain of Messine (abyssal being used here in its topographic meaning, that is to say a central basin away from the coast), and the Matapan South trench, to the south-west of the Peloponnesus. Samples were taken using an epibenthic drag with an automatic closing system enabling the catch of pelagic animals during the haulback and the loss of benthic samples.

Distribution of Cumacea in the deep Mediterranean
Provedor de dados: 5
Autores: Reyss, Daniel.
Cumacean Crustacea are an important faunal component of the deep-sea benthos of the Mediterranean. Thirty-three species have been collected from bathyal and abyssal depths and eight of these were new. Faunal composition is closely related to the North Atlantic cumacean fauna, especially to that of the Bay of Biscay. Mediterranean endemism is found for species occurring at depths of more than 2000 m. Trophic conditions and species diversity in the deep Mediterranean (2000-3000 m) are similar to those occurring in the North Atlantic between 4000 and 5000 m depth. [NOT CONTROLLED OCR]

Nos études sont suivies volontairement en des stations précises sur plusieurs années. Elles montrent indubitablement des changements importants repérables à la fois qualitativement et quantitativement. En 4 à 5 ans, on constate une dérive d'ensemble vers l'enrichissement à la fois en biomasse et en production, avec par contre des fluctuations saisonnières de plus en plus accentuées à des niveaux bionomiques comparables. Cette évolution est-elle en relation3 avec des phénomènes cycliques de longue période de l'ordre de 10 années, marquant les termes progressifs d'une succession classique, ou résulte-t-elle plus vraisemblablement d'une occupation de plus en plus poussée du littoral, de son urbanisation et de la progression des rejets industriels, d'une...

Etude morphologique du loup Dicentrarchus labrax L. de la region de Sete
Provedor de dados: 5
Autores: Barnabe, Gilbert.
Sampling of a population of D. Labrax was one with spear diving catches. Morphometric and meristic data were used to calculate a biometric index. This index showed that all the bass of the Sete area belong to Dicentrarchus labrax, even if they were black spotted on the upper part of the body. Morphology was slightly different according to sex, but sex determination was not always possible using morphometric data. This inshore population shows some morphological characteristics (branchiospine and lateral line scale number) different from the data collected on the same sp along the Maroc Atlantic coast by Gravier, 1961.

Researchers have studied the number of rays in the dorsal and anal fins, the number of branchiospines and of vertebrae of the anchovies of the Tunisian coast. Regarding the number of vertebrae, the anchovies of the North West belong to the 'West Mediterranean' group and those of the North East and South East to the 'East Mediterranean' group, according to Fage's classification. The anchovies found in Lake Ishkeul are well individualised morphologically and biologically speaking and could be classified in the large group of the anchovies living in Mediterranean brackish waters; the number of their vertebrae is slightly inferior to that of the groups living in the neighbouring sea waters.

The possibility of cultivation of the giant kelp Macrocystis pyrifera was successfully experienced in France on the north coast of Brittany. In order to evaluate the possibility of eventual acclimation on the French shore, study tour was undertaken on the Californian and Chilian coasts on main kelp beds. Effects of such beds on general ecology, fish resources, sportfishing, navigation, beach cleanliness, and alginates industry are analyzed. Factors controlling kelp distribution and hazards of wide distribution are discussed. Macrocystis seems to be able of developing and maintaining a large standing crop and to contribute to a large and stable associated fauna. The advantage of enhancing fishing greatly outweight the minor disadvantage of navigational...

Régime alimentaire et pourcentage de survie chez la larve de turbot (scophtalmus maximus (L.))
Provedor de dados: 5
Autores: Girin, Michel.
The authors who obtained the first metamorphosis during rearing of turbot larvae in 1972, in Great -Britain (Jones, Alderson and Howell, to be published), and in France (Girin, 1972) could not determine precisely the factors of their success. The great diversity, in shape and size, of the ponds used makes us think that the fishes' diet is the key to the issue. An experiment focusing on this issue had confirmed the importance of the daily food ration during the first 20 days following hatching (Girin, 1973). But a food catching problem seemed to add on to the food ration issue during the metamorphosis, leading to a halt in the rearing.

A contribution to the intraspecific systematics of Bufo bufo (Linnaeus, 1758) (Amphibia)
Provedor de dados: 16
Autores: Lange, L. de.
A biometrical analysis of preserved specimens of Bufo bufo, supplemented by a detailed examination of the shape of the skin warts, was performed in order to ascertain the taxonomic status of the form described as B.b.spinosus. Indications of a N.-S. clinal variation in the formation of wart thorns and in allometric relations of body elements were found. The validity of the form as a distinct subspecies seems accordingly very doubtful.

Cycles annuels de Gammarus duebeni duebeni Liljeborg, 1852, et de Gammarus pulex pulex (Linne, 1758) le long de la cote française du Boulonnais
Provedor de dados: 16
Autores: Beld, F.A.J. van den.
1. The life-cycles of Gammarus duebeni duebeni Liljeborg and G. pulex pulex (Linnaeus) have been studied in three stations (2 in fresh waters on the cliff coast, 1 in rockpools) on the French Channel coast, through monthly sampling during a good year. In every sample, the number of precopulae have been counted, and physico-chemical environmental factors, such as Ca++-contents, chlorinity, pH, and temperature, have been measured. The samples have been tested on homogeneity, after which the cephalic length was measured. Likewise, the sex and the stage of development (females either or not in reproductive stage, males, juveniles) have been determined. 2. In G. d. duebeni as well as in G. p. pulex there appears to exist a linear correlation between the total...

The Echinogammarus berilloni-group, a number of predominantly Iberian Amphipod species (Crustacea)
Provedor de dados: 16
Autores: Pinkster, Sjouk.
The morphological diversity within the species Echinogammarus berilloni (Catta, 1878), stressed by Spandl (1926), Margalef (1956) and Pinkster (1969) was a motive to sample systematically in drainage systems of the Iberian peninsula and of great parts of France. It became clear that E. berilloni in reality was the collective name for a group of at least 10 species, all of them with their own, restricted distribution area. Only one of these species, the real E. berilloni, inhabits a much larger area, including the major part of France, the Channel islands, Belgium, Luxembourg, the southern part of the Netherlands, and south-western Germany. In this study the characters of the E. berilloni-group are discussed and comparative descriptions are given of all...

The generic identity of Xanthostemon brachyandrus C. T. White: Lindsayomyrtus novum genus (Myrtaceae)
Provedor de dados: 16
Autores: Hyland, B.P.M.; Steenis, C.G.G.J. van.
Two decades ago the senior author was urged by the West New Guinea Forest Service to name a rather common canopy tree of New Guinea and the Moluccas. Among two dozen collections there was only one in flower, from the island of Ceram. Though the species was certainly new for Malesia, the absence of fruit explained his hesitation to refer it to one of the genera of the Tristania-Xanthostemon-Metrosideros complex to which it clearly belonged. It was finally described as Metrosideros nigroviridis Steen., the specific epithet alluding to the sepia-coloured twigs and conspicuously green-drying leaves. Finally, about 1960 a fruiting specimen collected by Chr. Versteegh came to hand (BW 4702) which showed by its indehiscent nature and fleshy pericarp that it could...

Critical revision of Botrytis-like genera leads to recognition of Botrytis, Chromelosporium, Glischroderma and Ostracoderma. Phymatotrichum is synonymized with Botrytis, and previously assigned species are reconsidered. Six new genera are recognized: Pulchromyces (for Phymatotrichum fimicola Dring); Phymatotrichopsis (for Phymatotrichum omnivorum Duggar); Streptobotrys, Amphobotrys, and Verrucobotrys (for conidial states of the Sclerotiniaceae); Dichobotrys (for the conidial state of Operculate Discomycetes of the genus Trichophaea). Hyphelia terrestris Fr. and related species, including conidial states of some Operculate Discomycetes of the genus Peziza, are placed in Chromelosporium.

A new species of notodelphyid copepod associated with Ρterygascidia longa (Van Name, 1918) from the Basilan Strait, Philippines
Provedor de dados: 16
Autores: Ooishi, S.; Illg, P.L.
In research on the two ascidians Pterygascidia mirabilis Sluiter, 1904, and P. longa (Van Name, 1918), Tokioka (1971a, b) found some copepods associated with both species. We were given the opportunity to examine these crustaceans. The copepod described below, Goniodelphys tokiokai n. sp., is a notodelphyid inhabiting the branchial sac of P. longa. The material was obtained from a few specimens among 20 ascidians which were collected by the Snellius Expedition on 5 September 1929, and deposited at the Rijksmuseum van Natuurlijke Historie, Leiden. As the copepods living in P. mirabilis belong to a family other than Notodelphyidae they will be reported in a future paper. We wish to express our warm thanks to Dr. Takasi Tokioka, of the Seto Marine Biological...

A revision of Caltha (Ranunculaceae)
Provedor de dados: 16
Autores: Smit, Petra G.
The family of the Ranunculaceae, although a large one (ca. 1200 species) occurring almost throughout the world, is generally regarded as a very natural one. The only genera with a recently more or less disputed position are Circaeaster, Glaucidium, Hydrastis, Kingdonia, and Paeonia. The others may at present all be considered to be ‘true’ Ranunculaceae. Various botanists have studied the delimitation of these genera, their affinity and phylogenetic links. Their ideas are often widely divergent. There is no need to go into the subject here, but some opinions on the place in the system of Caltha may be reviewed.

Strobilation in a mollusc; the development of aberrant stages in Clio pyramidata Linnaeus, 1767 (Gastropoda, Pteropoda)
Provedor de dados: 16
Autores: Spoel, S. van der.
The occurrence of aberrant stages in the protandric hermaphrodite Clio pyramidata is considered in relation to the sexual cycle of this species. The anatomy of the juveniles, males and females is shortly discussed especially with regard to their sexual organs. The anatomy of the developing (the normal-complete) and of the growingaberrant stage is briefly reviewed. It is shown that the aberrant stage is formed by strobilation of a normal specimen, probably as a result of less favourable environmental conditions. As the most important conclusions it can be stated that: 1) the aberrant stage described by van der Spoel (1962) is a normal stage in the life cycle; 2) the aberrants are most abundant in the population in the months before the reproductive peaks;...

Enige ervaringen met Juncus tenageia L.f. in de leemputten bij Udenhout (N.-Br.)
Provedor de dados: 16
Autores: Londo, G.
In former times Juncus tenageia was a rather common species in various parts of the Netherlands. Now it has become very rare as a result of the lowering of the waterlevel and of manuring. Excavation of loam near Udenhout (province N.-Brabant) resulted in a new habitat for the species. It was evident that J. tenageia is only present when the excavated loam was flooded in the last winter or spring. A rising waterlevel in the vegetation season, as was the case in 1972, resulted in the absence of this species.

A revision of Digitaria Haller (Gramineae) in Malesia. Notes on Malesian grasses VI
Provedor de dados: 16
Autores: Veldkamp, J.F.
In this paper a revision is given of the Malesian species of the Crabgrasses, or Digitaria Haller ( Gramineae). The research was done at the Rijksherbarium, Leyden, while many other Herbaria were shortly visited; some field work was done in Indonesia, Australia, and Papua-New Guinea. The foundation for the study in this large and cosmopolitan genus must be Henrard’s monumental work ‘Monograph of the genus Digitaria’ (1950), which is therefore extensively cited and discussed. Henrard based his division in sections, 32 in the subgenus Digitaria, with an emphasis on the amount of spikelets per grouplet and the various types of hairs, but such a subdivision appears difficult to maintain. As only part of the species of Digitaria occurs in Malesia, not...

The shape of the surface hairs decides the affiliation to the genus. Since species with branched as well as with unbranched surface hairs are comprised in the genus Henningsomyces O.

Lilium bulbiferum L. in Limburg. De korte mededeling in Gorteria 6(8), 1973, p. 140 betreffende de recente vondst van Lilium bulbiferum L. subsp. croceum (Chaix) Arcang. deed mij herinneren aan het feit, dat omstreeks 1943 Dr. A. de Wever te Nuth mij een bloeiende tak van deze soort stuurde uit de omgeving van Doenrade, van een roggeakker. De eigenaar van deze akker had daar jarenlang steeds rogge verbouwd. Een bloemist had hem ƒ 25,— geboden om de bollen te mogen rooien. Toen de eigenaar hierop niet wenste in te gaan, werden een paar nachten later alle planten eruit getrokken en werd de rogge platgetrapt. Het exemplaar, dat De Wever mij toestuurde, is opgenomen in mijn herbarium, dat onlangs werd afgestaan aan het Instituut voor Systematische Plantkunde...

A la suite d’une nouvelle analyse du processus de la pléonisation du péréion (Serban, 1972), on arrive à la conclusion selon laquelle les remaniements présents au niveau des 3 derniers péréionites des Bathynellacés sont dus à la position différente des segments génitaux dans les deux sexes.

A revision of Caltha (Ranunculaceae)
Provedor de dados: 16
Autores: Smit, Petra G.
The family of the Ranunculaceae, although a large one (ca. 1200 species) occurring almost throughout the world, is generally regarded as a very natural one. The only genera with a recently more or less disputed position are Circaeaster, Glaucidiutn, Hydrastis, Kingdonia, and Paeonia. The others may at present all be considered to be ‘true’ Ranunculaceae. Various botanists have studied the delimitation of these genera, their affinity and phylogenetic links. Their ideas are often widely divergent. There is no need to go into the subject here, but some opinions on the place in the system of Caltha may be reviewed.

The wood anatomical range in Ilex (Aquifoliaceae) and its ecological and phylogenetic significance
Provedor de dados: 16
Autores: Baas, P.
The wood anatomy of 81 species of Ilex is described in detail. The wood anatomical range encountered is presented in a generic description (p. 196). Data on ontogenetic changes in vessel member length and number of bars per perforation are given for three species. The great amount of variation in mainly quantitative but also in some qualitative features is hardly or not related with subgeneric classification but with latitudinal and altitudinal distribution. In both the northern and southern hemisphere and in both the Old and New World, temperate and subtropical species are characterized by conspicuous growth rings, numerous narrow vessels, relatively short vessel members and few bars per perforation plate, conspicuous spiral thickenings on both vessel and...

Additional Miocene to Pleistocene rhinoceroses of Africa
Provedor de dados: 16
Autores: Hooijer, D.A.
The purpose of the present paper is to place on record data on fossil Rhinocerotidae from Africa not included in earlier papers. Material has turned up in Africa in great quantities over the last decade, much from beautifully calibrated sequences especially in Ethiopia and the Baringo area of Kenya. Dreary descriptions of fossil teeth and bones are simply a prerequisite to construct, as is my aim, a sort of phylogeny of the rhinoceroses of Africa comparable to those long established for Europe or America. We have at this moment seven genera and a dozen or so species of Rhinocerotidae from the Neogene and the Quaternary, which will be dealt with below. My research in East and South Africa has been supported by grants-in-aid from the Wenner-Gren Foundation...

About 10 years ago no recent records of Gagea villosa were known for the Netherlands; formerly it occurred in more than 30 hour-squares. Since 1969 the species has been recorded from 4 localities, in each case growing in rather thin lawns or on little trodden paths. It is possible, that the species may be found in more hour-squares in the Netherlands, as G. villosa can survive vegetatively for long periods.

Clio pyramidata Linnaeus, 1767 forma convexa (Boas, 1886) (Mollusca, Pteropoda)
Provedor de dados: 16
Autores: Spoel, S. van der.
The pelagic fauna of the Red Sea shows special variation induced by its isolated character (Van der Spoel, 1971). Clio pyramidata from the Red Sea is usually incorrectly referred to as the tropical forma lanceolata (Lesueur, 1813) or the typical forma pyramidata Linnaeus, 1767. Some large samples with C. pyramidata from the northern Red Sea made it possible to establish the correct identity of these populations. Though special variation, like described for Diacria and Cavolinia species (Van der Spoel, l.c.), is found for Red Sea populations of C. pyramidata, the populations are not separated as an endemic taxon as the specimens resemble closely Clio pyramidata forma convexa (Boas, 1886) (figs. 1-4). The anterior parts are almost identical to those of...

Lung-anatomy: aid in Chameleon-taxonomy
Provedor de dados: 16
Autores: Klaver, CH.J.J.
Chamaeleo pumilus is often classified in a separate genus Microsaura or Lophosaura, partly because of differences in lung-structure as compared with a small number of other species. The validity of this assumption, that is questioned, is investigated by studying the lungs of 17 species. Apart from the two lung-types of Chamaeleo chamaeleon and Chamaeleo pumilus already known, many other clearly distinguishable lungtypes were found. As similarities in lung-structure tend to coincide with the relationships distinguished by taxonomists, the lungs proved to be a useful character in this yet systematically difficult group. The extensive variation is discussed in view of various processes in action during the evolution of lungs. Thus it became possible to...

Probably Lower Paleozoic quartzo-pelitic schists with bands of feldspathic schists, white and black quartzites, graphite schists and amphibolites have been folded twice. Hercynian regional metamorphism led to porphyroblastic growth of chlorite, albite, biotite, garnet, staurolite mainly between F1 and F2. Andalusite porphyroblasts are related to Hercynian granite intrusions of varying age with respect to F2. An isograd map of biotite, garnet, staurolite and andalusite is presented. Structures elucidating the relations between deformation phases and metamorphic mineral growth are discussed.

A new genus and species of copepod crustacean, Nannallecto fusii, is recorded parasitic on the pteropod, Pneumodermopsis (Pneumodermopsis) paucidens (Boas, 1886), from a surface tow off French Guiana. The parasite is obviously related to the only other adult copepod associate known from pteropods, the recently discovered Micrallecto uncinata Stock, 1971, and it appears to belong likewise to the family Splanchnotrophidae. The present new genus differs chiefly from Micrallecto in the presence of strong maxillipeds.

In any new region the knowledge of the spider fauna, or of any other group of organisms, has to go through three successive stages. In the beginning there is a period of descriptive activity with many new species recorded and named, in the past usually by several authors independently. In the Nearotic Region this stage may have ended for New England, but this is hardly true for the Far West and the southeastern part. In particular the names of Emerton, McCook, Keyserling, Banks, Petrunkevitch, Crosby, Bishop, Chamberlin, and Ivie, not to mention many others, are forever associated with this period. By building up large collections and giving their finds to the world they have laid the foundations of New World Arachnology. The second stage I would call the...

On the ecology of Coenobita clypeatus in Curaçao with reference to reproduction, water economy and osmoregulation in terrestrial hermit crabs
Provedor de dados: 16
Autores: Wilde, P.A.W.J. de.
1. This paper deals with various aspects of the life-history, ecology, water management and osmoregulation of the West-Indian land hermit crab Coenobita clypeatus (Herbst) in Curaçao, Netherlands Antilles. 2. Land hermit crabs belonging to the family Coenobitidae may be considered as one of the most terrestrial forms of decapods. They are characteristic for tropical coasts and islands. Though C. clypeatus may be found in a variety of habitats they show a preference for areas with a relatively dry climate. In this respect habitats as found on the Leeward Group of the Lesser Antilles are representative for the species’ occurrence. In addition to populations of animals living on the coast, the ‘coastal animals,’ there are also individuals living in the...

Caridean Shrimps found in Land-Locked Saltwater Pools at four Indo-West Pacific Localities (Sinai Peninsula, Funafuti Atoll, Maui and Hawaii Islands), with the description of one new genus and four new species
Provedor de dados: 16
Autores: Holthuis, L.B.
At several occasions red coloured caridean shrimps have been reported from tropical land-locked saltwater pools. These pools are situated at some distance from the sea, but, because the level of the water rises and falls with the tides, must have subterranean connections with the sea. The shrimps belong to species that so far have not been found outside this special type of habitat, although some have a rather extensive geographical distribution. Apart from the peculiar habitat in which they are found and apart from their red coloration, there is very little that these species have in common. The 11 species so far found exclusively in these pools belong to 9 different genera and to 5 different families (see also Holthuis, 1963; Chace &amp; Manning, 1972)....

Some remarks on the classification and differentiation of Moraceae
Provedor de dados: 16
Autores: Berg, C.C.
With the appearance in 1889 of Engler’s treatment of the Urticales in “Die natürlichen Pflanzenfamilien” there came a pause in the interesting development of the classification of this group, which was defined, albeit somewhat vaguely, by A.L. de Jussieu in 1789 in his “Genera Plantarum” as the order Urticeae. Since the 1830’s, many, including Gaudichaud, Trécul, Miquel, Bureau, Eichler, Baillon, and Bentham, have contributed to the establishment of the Engler system which until recently has been generally accepted. An important moment in this history was the appearance of Trécul’s treatment of the then most problematical group, the “family” Artocarpeae. Trécul (1847) considered the “families” which at that time were distinguished within the “class”...

On the comparative anatomy and function of the nasal tract in odontocetes (Mammalia, Cetacea)
Provedor de dados: 16
Autores: Schenkkan, E.J.
In the study of phonation in odontocete cetaceans and particularly that of echolocation by means of sonar, a great number of conflicting hypotheses have been advanced regarding the correlation of sound production with the many anatomical features that are to be found in the upper respiratory tract. The present paper follows a new approach via finding out if, and how, the various structures had evolued from the condition in the relatively primitive River Dolphins to the more highly specialized pelagic species. An introduction to the general anatomy of the upper respiratory tract is given, relating it to work previously published on this subject. A historical review of the various theories of sound production establishes the essence of the existing...

The palynology of some Palaeogene deposits between the Rio Esera and the Rio Segre, southern Pyrenees, Spain
Provedor de dados: 16
Autores: Haseldonckx, P.
In this article the results of a palynological investigation of Palaeogene sediments in the Spanish Pyrenees are discussed. A statistical analysis is used to interpret the counts in the absence of extensive biological and stratigraphical information about the species studied. A broad picture of the climatic changes could be reconstructed together with the different vegetational zones in the coastal swamp area. The presence of Nypa and Nothofagus, probably allochthonous, is at least striking. The biozonation is fitted into a stratigraphic framework based on Foraminifera. A new genus and some new species are described and discussed under Systematics together with all species mentioned in this investigation. A Fortran IV computer programme for the statistical...

Copepoda of the family Lamippidae from the western Atlantic and the Caribbean
Provedor de dados: 16
Autores: Stock, Jan H.
The Lamippidae form a rather homogeneous family of copepods endoparasitic on octocorals. The great majority of the species (17 out of 24) is described from the Mediterranean Sea. These species are relatively well-known, thanks to the efforts of DE ZULUETA (1908, 1910, 1911) and BOULIGAND (various papers, summarized in BOULIGAND, 1966). Outside the Mediterranean, Lamippidae have only incidentally been recorded, from the eastern Atlantic (European coasts, Sierre Leone), Indonesia, the Red Sea, and the Antarctic (references in HUMES, 1957, BOULIGAND, 1960, and STOCK, 1972). Not a single species was recorded hitherto from the western Atlantic or Caribbean region. Entire specimens were studied and measured in lactophenol; the appendages were dissected and...

The wood of Amentotaxus
Provedor de dados: 16
Autores: Miller, Howard J.
Controversy over the taxonomic relationship of the Taxineae with the Coniferineae has created a new interest in the field of wood anatomy. This has been reflected by the flurry of investigations being conducted in families such as the Podocarpaceae. The systematic position of Amentotaxus is somewhat uncertain (see Keng, 1969). While many authors place Amentotaxus in the Taxaceae, this genus has also been referred to the Cephalotaxaceae or even considered to represent a separate family, the Amentotaxaceae. When Kudo and Yamamoto (1931) described this last family, it was considered to be represented by only a single species, Amentotaxus argotaenia (Hance) Pilger. In his revision of Amentotaxus Li (1952) recognized four species. However, the description and...

Autores: Boersma, Kerst Th.
Conodont faunas were collected from the Devonian and Lower Carboniferous in an area ranging from the Rio Fsera (prov. of Huesca) in the west to the Rio Llobregat (prov. of Barcelona) in the east. Most conodont zones and -Faunas recognized in Germany and Spain could be distinguished. The ages of the formations distinguished in the Compte-, Sierra Negra s.l.- and Renanué sub-facies of the Southern facies (Mey, 1968a) could be indicated quite accurately. The formations in the various sub-facies are lithostratigraphically and chronostratigraphically correlated. There is very strong evidence of a Tournaisian hiatus of changing extent, while the existence of a small Lower Frasnian hiatus is probable and the existence of a Siegenian hiatus in the Compte subfacies...

A new genus of resupinate polypores, Donkioporia Kotl. &amp; Pouz., is proposed for the fungus chiefly known under the name of Poria megalopora (Pers.) Cooke. Since the oldest name of the species appears to be Boletus expansus Desm., the new combination Donkioporia expansa (Desm.) Kotl. &amp; Pouz., is proposed. The genus is characterized microscopically by a trimitic hyphal system possessing both thin- and thick-walled generative hyphae with clamp-connections. The internal layer of the walls of some of the thick-walled generative hyphae gives an amyloid reaction.

Het Myriophyllo verticillati — Nupharetum bij Denekamp

Autores: Weeda, E.J.
Myriophyllum verticillatum and Nuphar lutea were observed growing together in the Almelo- Nordhorn Canal near Denekamp (Prov. Overijssel) together with among others the rare Utricularia neglecta. The composition of the aquatic vegetation found in this canal strongly corresponds with that of the Myriophyllo-Nupharetum described by OBERDORFER (1957). The occurrence of this association, as interpreted by the author, is in contradiction to the findings of WESTHOFF &amp; DEN HELD (1969), who state that the association is lacking in the Netherlands. However, it is possible that in the Netherlands the association is restricted to this described locality.

Provedor de dados: 16
Autores: Philipson, W.R.
Four specimens of an Araliaceous species collected in the Vogelkop Peninsula and a neighbouring area of SW. New Guinea are so distinctive as to require a new genus. The large, simple, oblanceolate leaves clustered at the ends of the branches recall the habit of Meryta, but the flowers do not share the highly distinctive features of that genus: in particular, they are hermaphrodite, the calyx is well-defined, and a distinct articulation occurs below the ovary. The technical floral and fruit characters are not unlike those of Polyscias (e.g. there is an articulation below the flower, the style arms are free, and the endosperm is smooth), but their general facies is unlike that genus, and this, together with the distinctive inflorescence and leaf, makes the...

In the Cyclopaedia of Malaysian Collectors and Collections, Mrs. M. J. van Steenis-Kruseman (Flora Malesiana I, I, 1950, 248a, 527b) stated that plants of Herb. Houttuyn, which Houttuyn had acquired from various collectors, were subsequently incorporated in other herbaria, that of Burman in particular. Merrill had questioned this in his work on Houttuyn (J. Arn. Arb. 19, 1938, 291—375, reviewed in Fl. Mal. Bull. no. 17, 1962, 906), as he could not locate a single sheet of Houttuyn’s collection. He only mentioned (l.c.p. 310) that in the Copenhagen Herbarium, in Herb. Vahl, there would be a fragmentary specimen of Myristica fragrans on the back of which was noted ‘ded. Houttuyn’.

Olisthostromes and other delapsional deposits, and their occurrence in the region of Moratalla (Prov. Of Murcia, Spain)
Provedor de dados: 16
Autores: Hoedemaeker, Ph.J.
In the first part of this publication an attempt is made to bring some order in the terminological chaos existing in the field of delapsion, which is the independent gravitating of rock material along sloping surfaces. The term olisthon is introduced for everything that has been delapsed. For the purpose of a rational and comprehensive classification of geological phenomena delapsion is introduced as a separate class between tectonization and sedimentation. Special emphasis is laid upon the concepts of olisthostrome and olistholith, which are redefined. The principles of the mechanics involved in delapsional processes are discussed. In the second part emphasis is laid upon the description of the olisthostromes, olistholiths, reversely graded mud flow and...

Autores: Schalke, H.J.W.G.
Palynological data and other evidence suggest that the Upper Quaternary of the Cape Flats area can be subdivided chronostratigraphically into units that may be correlated with those of the Northern Hemisphere. Five intervals have been identified in the Middle Pleniglacial and formal names are introduced for these intervals. During three of them, the MILNERTON, KILLARNEY and BLOUBERG intervals, the vegetation had a xerophytic character and is comparable with that of the Holocene. During the intermediate periods, the SALTRIVER and DIEPRIVER intervals, an extension of the mixed Podocarpus (Knysna) forest to the Cape Flats area took place. These changes in vegetation can be explained by differences of effective precipitation. Two periods of sedimentation,...

Abnormal sinistrorsity in the Marginellidae (Gastropoda)

Two species of Marginellidae, Closia angustata (Sowerby, 1846) and Hyalina effulgens (Reeve, 1865), are added to Dance’s list (1972) of abnormal sinistral marine gastropods. Including four other records the total number has increased to 70 species. Of these, 29 belong to the Marginellidae, which occur in all tropical and subtropical seas. There is no explanation so far for this very high percentage of sinistral species in a single family. Abnormal sinistrorsity seems to be related to the evolution of the Gastropoda: sinistral specimens are unknown in the primitive order of the Archaeogastropoda, they are rare in the Mesogastropoda (8 species), and less rare in the Neogastropoda (62 species). Within the order of the Neogastropoda, the superfamily Volutacea...

Leaf epidermal features (mostly studied in cuticular macerations) of 146 specimens, belonging to c. 33 species of all the 6 genera of the Winteraceae are described in detail. Typical for most representatives is the occurrence of alveolar material of cutinaceous nature overlying the cuticle proper, and usually occluding the stomata. Special attention is paid to the appearance, distribution and significance of this alveolar material. The taxonomic value of the characters described is discussed. All genera show an overlap with one or more genera in a varying number of leaf epidermal characters, so absolute diagnostic characters at the genus level are absent. It is also impossible to recognize distinct groups of genera. Exospermum and Belliolum are entirely...

A revision of Harmsiopanax (Araliaceae)
Provedor de dados: 16
Autores: Philipson, W.R.
Harmsiopanax is a small structurally isolated genus confined to the Malesian Archipelago. The three species here recognized are uniform both in their vegetative and their reproductive features. It has long been recognized that some of the characters of this genus are anomalous within the Araliaceae and a return to its earlier position within the Umbelliferae would have something in its favour. The monocarpic habit is unknown elsewhere in the Araliaceae, but is not uncommon in the Umbelliferae. The character of the fruit, which splits into two dry mericarps, closely approaches the fruit of the Umbelliferae, and the vascularization of the gynoecium (Philipson, 1970) is also characteristic of that family. However, the structure of the leaf-base, the tree...

The status of two species of migrant swifts in Java and Sumatra (Aves, Apodidae)
Provedor de dados: 16
Autores: Mees, G.F.
Apus pacificus pacificus (Latham) The occurrence of Apus pacificus in Java, as a migrant from the north, was established by Vorderman (1900), who collected a specimen in 1896: "in de Preanger, bezuiden de Salak". Soon afterwards, the species was also recorded by Bartels (1902, 1906). In later years specimens from Java were generally listed as belonging to the nominate race (Bartels Jr. &amp; Stresemann, 1929; Chasen, 1935; Kuroda, 1936; Hoogerwerf, 1948). Deignan (1956) identified a specimen from the Semangko Pass, Malaya, as belonging to the race Apus pacificus kanoi Yamashina, and subsequently Vaurie (1965: 654, 655) expressed the opinion that birds reported from the southern Malay Peninsula, Sumatra and Java are "probably" referable to this subspecies,...

On the phylogenetic position of the genus Boucotinskia Brunton and Cocks, 1967 (Spiriferida)
Provedor de dados: 16
Autores: Krans, Th.F.
A morphological comparison of Boucotinskia Brunton &amp; Cocks, 1967 and Kozlowskiellina Boucot, 1957 makes a phylogenctic relationship between the two genera obvious. Boucotinskia is placed in the subfamily Cyrtinopsidinae. The subfamily Cyrtinopsidinae is probably very closely related to the Eospiriferinae and the Cyrtiinae.

A Bibliography of Pelagic Tunicates
Provedor de dados: 16
Autores: Waard-Pouw, G. van; Soest, R.W.M. van.
The present bibliography on pelagic Tunicates has been compiled over a period of 4 years, mainly by the first author. It is meant, not as an official publication, but as a working aid for students of pelagic Tunicates. It comprises about 1300-1400 different titles of books and articles. For obvious reasons the mere listing of all those titles in alphabetical order would be impractical for specialized demands. Splitting this list in as many subheadings as possible in a way like the Zoological Record would be ideal. However, many articles and books are difficult to place under one heading; the same titles would have to be mentioned under a number of different headings. With as many headings as possible this would mean a multiplication of the 1300-1400 titles...

Neophocaena phocaenoides asiaeorientalis (Pilleri &amp; Gihr, 1973), a synonym of the preoccupied name Delphinus melas Schlegel, 1841 (Notes on Cetacea, Delphinoidea VII)
Provedor de dados: 16
Autores: Bree, P.J.H. van.
The name Delphinus melas, given by Schlegel (1841) to a Finless Porpoise from Japan, is a junior homonym of Delphinus melas Traill, 1809 (now: Globicephala melaena). The generic name Neomeris Gray, 1846 is preoccupied by Neomeris Costa, 1844; the valid nomen novum for Gray’s genus is Neophocaena Palmer, 1899. Neomeris asiaeorientalis Pilleri &amp; Gihr, 1973 belongs to the same taxon as described by Schlegel. Therefore the correct name of the Japanese form described by Schlegel is Neophocaena phocaenoides asiaeorientalis (Pilleri &amp; Gihr, 1973).

Investigations of the marine pelagic tunicate genus Thalia Blumenbach, 1798, resulted in the description of two new species, T. cicar and T. sibogae. In addition the three known subspecies of Thalia democratica (Forskål, 1775) are considered full species. The distribution of these species, including Thalia longicauda (Quoy &amp; Gaimard, 1824), is given and a key to the solitary and aggregate zooids of the species is added. The specific status of the six taxa of the genus is discussed.

The hydrogeology and hydrochemistry of Lower Rhine fluvial plain
Provedor de dados: 16
Autores: Geirnaert, W.
The water-bearing strata in the area under study consist mainly of fluviatile Pleistocene. The base is formed by the marine Plio-Pleistocene, the top by the Holocene clay and peat deposits. The chemical composition of the ground-water in this aquifer depends on processes related to the geological history, not on the type of sediment. The most important of these processes is cation exchange, which occurs in two ways. When fresh water replaces salt water in the aquifer, an exchange takes place between the Ca2+ ions from the ground-water and the exchangeable Na+ ions from the sediments. The reverse process takes place when sea-water infiltrates a sediment with fresh ground-water: the Na+ ions from the sea-water are exchanged for Ca2+ ions from the sediments....

Basidial morphology and hymenophoral development in Rhizopogon
Provedor de dados: 16
Autores: Talbot, P.H.B.
Species currently assigned to Rhizopogon Fr. &amp; Nordh. can be divided into at least two groups on the basis of basidial morphology and hymenophoral development. It is desirable that two genera should be recognized but problems of typification preclude a formal proposal to this effect. One group contains species with clearly dimerous basidia which are commonly associated with swollen, thickened or gelatinized basidioles and often arise laterally from these. The other is composed of species with clavate or cylindrical non-dimerous basidia which are not associated with modified basidioles. These observations show the potential value of using the developmental anatomy of the hymenophore in the taxonomy of Gasteromycetes. Fresh specimens in various stages of...

The comparative anatomy of the nasal tract and the function of the spermaceti organ in the Physeteridae (Mammalia, Odontoceti)
Provedor de dados: 16
Autores: Schenkkan, E.J.; Purves, P.E.
The nasal complex of Kogia has been compared with that of Physeter and shown to be homologous with that of less specialized ondotocetes. The nasal complex of the Physeterids is structurally related to that of the Platanistids and Ziphioids. The spermaceti organ unique to the Physeteridae forms a part of the functional morphology of the right naris and is not a bilaterally symmetrical structure like the melon of other odontocetes. Separation of the two nares in the Physeteridae is caused by the asymmetrical development of the spermaceti organ. In Kogia part of the musculature of the left naris actuates the opening of the right naris, a feature unique amongst the Mammalia. The right naris is not used in external respiration but forms an air reservoir...

The Myachkovian and Kasimovian chronostratigraphic units in the U.S.S.R. are correlated with similar units as used in western Europe. This correlation is here established through northwestern Spain, where fusulinid faunas and plant fossils enable a comparison with the U.S.S.R. and western Europe. It is shown that the lower- and upper limit of the Myachkovian correlate with some level in the Westfalian D and the middle Cantabrian respectively and that the top of the Kasimovian may probably be equated with some level in the Stephanian B.

On the validity of Alcyonium siderium Verrill (Coelenterata : Octocorallia)
Provedor de dados: 16
Autores: Verseveldt, J.
INTRODUCTION Verrill (1879: 199-200) described two specimens of Alcyonium collected on the Fishing Bank, east of Cape Cod, Massachusetts, in 80 fathoms. According to him "they form low, thick, lobular masses", "the base is somewhat spreading" and "the division into rounded or flattened lobes takes place close to the base". He is of opinion that "if not identical with A. digitatum of Europe, it is at least very closely related". More than forty years later Verrill (1922: 20) returns to this question. This time he gives a drawing of one of these American colonies (his textfigure 3), and he has changed his mind regarding the relation to A. digitatum. He now thinks the species is "distinct from the common European species, A. digitatum, to which it is nearly...

Een hydrobiologische inventarisatie van sloten in het Oude Land van Strijen en de St. Anthonie-polder (Hoekse Waard)
Provedor de dados: 16
Autores: Nieukerken, E.J. van; Velde, G. van der.
A hydrobiological description of eight ditches in the Dutch inland polders "Oude Land van Strijen" and "St.-Anthoniepolder" (province of South-Holland) is given. The flora and macrofauna (table 2 and 3) have been studied in July and October 1971. A few chemical data (chloride-content and conductivity) of the water are presented. In the northern part of the area the percolating water is fresh due to the influence of the "Binnenbedijkte Maas", one of the few real freshwater lakes of the Deltaic region. In the southern part it is brackish due to the influence of the „Hollands Diep". The bottomprofile of the polders shows heavy river-clay poor in chalk (upper 40-100 cm) on peat. The examined ditches are hardly polluted and the water is clear. On the bottom of...

This study concerns the petrology of the Mellid area, the SE portion of the outer zone of the Ordenes Complex which is one of the upthrusted Precambrian complexes in the axial zone of the Hercynian orogen in Galicia, NW Spain. An eugeosynclinal rock sequence is found containing units with different metamorphic evolutions. All units were affected by Precambrian tectonization and retrogressive metamorphism. This orogeny may be subdivided into three metamorphic and four deformation phases which caused definite changes in the mineralogical composition and the texture of the rock. The sequence of metamorphic phases, established in a granulite facies unit is as follows: the first phase of Precambrian metamorphism is characterized by the (hornblende-)granulite...

Serpulinae (Polychaeta) from the Caribbean: II – The genus Sclerostyla
Provedor de dados: 16
Autores: Hove, H.A. ten.
The genus Sclerostyla is better known from fossil records than from recent material (WRIGLEY, 1951; MÜLLER, 1970). This is not surprising, since Sclerostyla ctenactis is difficult to find, the tube usually being imbedded in the substrate. Such material was studied only by MÖRCH (1863) in the Zoologiske Museum, København; by AUGENER (1922) in the zoological museums of Berlin and Hamburg; by TREADWELL (1929) in the American Museum of Natural History and by WRIGLEY (1951) in the Allan Hancock Foundation, Los Angeles. The specimens have been reexamined. Additional specimens were collected by Dr. P. WAGENAAR HUMMELINCK (1955, 1963—64) and by the author (1970). This material, as a rule, was preserved with formaldehyde and, after a short period, transferred to...

Provedor de dados: 16
Autores: Olesen, N.Ø.; Hansen, E.S.; Kristensen, L.H.; Thyrsted, T.
Sediments and volcanic rocks (ophiolites) all of early Palaeozoic age were metamorphosed, multiply deformed, and intruded by igneous rocks during the Caledonian orogeny. At least six deformation phases including late faults are recognized. There is no simple correlation between deformation phases and tectonic style. The second deformation phase (D2) is accompanied by Barrovian type metamorphism, ranging from biotite to sillimanite grade, and transposes earlier surfaces into a new foliation, which is itself folded on a regional scale. The transposition foliation varies from crenulation cleavage to schistosity. Basic intrusives are rimmed by contact metamorphic aureoles also of syn-D2 age. Acid intrusives are of syn- to post-D2 age. Structural and...

Autores: Serène, R.
The author examined material of Sesarma and Macrophthalmus in the collection of the Leiden Museum during a visit made in 1970. His main purpose was to check specimens identified by previous authors and take photographs of some of them. For the Macrophthalmus species, the work of Barnes (1971) has in the mean time cleared up some of the problems which he was considering, this is especially true for M. brevis and M. quadratus. The status of some other species remains unsatisfactory, however, and the second part of the present note is devoted to one of those: Macrophthalmus telescopicus of authors. The same visit provided the author with an opportunity to examine a collection of unidentified material from New Guinea. A new species of Macrophthalmus sorted out...

Ultrastructure of the ascospore wall in Pezizales (Ascomycetes)—I. Ascodesmis microscopica (Crouan) Seaver and A. nigricans van Tiegh
Provedor de dados: 16
Autores: Merkus, Emily.
The development of wall layers and ornamentation of ascospores is studied with the electron microscope in Ascodesmis microscopica (Crouan) Seaver and A. nigricans van Tiegh. In both species a primary and a secondary wall are formed in succession. The primary wall differentiates into two layers, an inner endospore and an outer epispore. The secondary wall gives rise to patterns of ornamentation and is composed of membranous structures in a homogeneous matrix; the epiplasm seems to be involved in its formation. The reported differences in the development of ascospore ornamentation between these two species must be denied. Only the final patterns of ornamentation are different.

The South Asiatic Olethreutini (Lepidoptera, Tortricidae)
Provedor de dados: 16
Autores: Diakonoff, A.
Although a large number of Tortricoid species and several genera from the Indo-Malayan region have been described by earlier authors (Walker, Snellen, Walsingham, Meyrick, and a few others), no survey of the present group has ever been made. Edward Meyrick, the author of most of the new names, has never attempted a synopsis of the Olethreutinae. He made surveys of the Australian and New Zealand Tortricoidea (1911), but the results are too superficial for our modern standards. During a long sojourn, working and collecting in Java, I became greatly fascinated by that fauna. Having completed a number of preliminary studies of the subfamily Tortricinae (1939 et seq.), I turned next to the South Asiatic, especially Javanese, Olethreutinae. After a long delay...

Carboniferous Fusulinids of the Sama formation (Asturia, Spain) (I. Hemifusulina)
Provedor de dados: 16
Autores: Ginkel, A.C. van.
Deposition of the Sama Formation in the northeastern part of the Central Asturian Coal Basin most probably started in late Lower or early Upper Moscovian time and continued into the Myachkovian; a conclusion based wholly on investigation of the genus Hemifusulina. The Hemifusulina specimens occur all in siltstones and shales with a varying amount of lime, which apparently are the type of sediments laid down in conditions in which this genus could thrive. In the Sama Formation three Hemifusulina zones have been distinguished. A lower zone with H. ex gr. moelleri Raus. at the very base of this formation, a middle zone containing H. ex gr. communis Raus. and H. ex gr. dutkevichi (Putrya) and an upper zone with H. ex gr. graciosa (Lee).

This plant occurs together with S. piloglandulosa but inhabits a moister place in the mountain heath, viz. along a small streamlet, and it appeared to represent a miniature form of S. piloglandulosa. Besides, it had a further reduced number of ovules. It may be worthwhile to point out first the difference between dwarf forms and miniature forms.

Autores: Kliphuis, E.
Cytologioal investigations within Galium boreale L. showed the occurrence of tetraploids (2n=44) as well as hexaploids (2n=66) in Europe. Comparative morphological studies failed to demonstrate any differences in characters between the two cytotypes. Crosses between the tetraploid and hexaploid were unsuccessful, due to the occurrence of a strong and effective barrier between the two levels of ploidy. From a taxonomical point of view the two cytotypes are considered as to belong to the same taxon.

The paper reports on two small collections from the island of Pantelleria and the vicinity of Catania, Sicily. The former locality (mostly surface samples) yielded 52 specimens of 9 species in 9 samples, the latter 190 specimens of 14 species in 11 samples. One species of Nymphon proved to be new to science; it belongs to an uniunguiculate species group with N. longicoxa Hoek, 1881, and N. prolatum Fage, 1942, as nearest relatives. The question of Tanystylum in the Mediterranean is raised again and it is decided that there are two species, T. conirostrum (Dohrn, 1881) and T. orbiculare Wilson, 1878, respectively. The male of Ammothella longioculata Faraggiana, 1940 is figured for the first time in order to compare it with A. longipes (Dohrn, 1881)....

Provedor de dados: 16
Autores: Boersma, Kerst Th.
Scanning Electron Microscope photographs of Siphonodella cooperi and Siphonodella lobata suggest that basal pits decrease in size after having reached a maximum. Analysis of biométrie data and computed regression lines confirm this. The phenomenon is explained by postulating migration of the plane of separation between the conodont and the basal plate, downwards in the holoconodont.

Spiranthes spiralis (L.) Chevall. op Goeree. Ook in 1972 heeft Spiranthes spiralis op de bekende groeiplaats op Goeree weer rijk gebloeid. Op 2 september 1972 telden wij 993 bloeistengels. Opvallend was een lichte teruggang van het aantal bloeiende exemplaren ten opzichte van 1971 (1142 exx.), alsmede het feit dat de planten in hun ontwikkeling niet zover waren als op 22 augustus 1971, toen dus 11 dagen eerder werd geteld. Voor wijze van telling en beschrijving van het gebied zie Gorteria 5(11), 1971, p. 266—267.

Notes on some Corticioid lignicolous fungi associated with snowbanks in southern Arizona
Provedor de dados: 16
Autores: Gilbertson, R.L.
Seven species of corticioid Hymenomycetes that fruit on wood in snow or near the edges of snowbanks in southern Arizona are discussed. Basidiocarps of Coniophora corrugis and Corticium lepidum apparently develop only in snow. Athelia decipiens, A. epiphylla, Leptosporomyces galzinii, Confertobasidium olivaceo-album, and Byssomerulius hirtellus produce actively sporulating basidiocarps in snow, but also fruit readily during the late summer and fall rainy season.

Foraminiferal ecology in the Ria de Arosa, Galicia, Spain
Provedor de dados: 16
Autores: Voorthuysen, J.H. van.
SUMMARY The Ria de Arosa is a large inlet of the Atlantic in western Galicia, NW Spain. It is little influenced by river discharge, the salinity is therefore the normal one for sea water, 33-36°/oo. According to Cadée (1968) the rocks exposed on the coast are for for the greater part granites; the rest, especially on the northwestern and northern coast, being gneisses and micaschists. Seven foraminiferal facies could be made. The L/D ratio is extremely low. It varies from zero to 18.5; the medium ratio is 2.3. Transport of shells from the continental shelf into the bay is rather high and more or less confined to the outer bayzone. The Recent foraminiferal fauna of the Arosa Bay has a fairly large number of species in common with the littoral Pliocene and...

The section Pachylomidium (genus Fissidens). I. The species of tropical and subtropical South America
Provedor de dados: 16
Autores: Bruggeman-Nannenga, M.A.
The present paper is intended to be the first of a series on the species of Pachylomidium from all over the world. It has been prepared under supervision of Dr. P. A. Florschütz (Instituut voor Systematische Plantkunde, Heidelberglaan 2, Utrecht). The species of Pachylomidium are characterised by leaves which are completely or nearly completely bordered, with a nerve which nearly or completely reaches the apex, smooth cells and a pluristratose border. The species of this section grow exclusively near running water and are inundated during part of the year. Unfortunately there are some species which are more or less transitional between this section and other ones. I will deal with these problems more extensively in a following paper.

A study of the genus Paracaloptenus I. Bolívar, 1876 (Orthoptera, Acridoidea, Calliptaminae)
Provedor de dados: 16
Autores: Willemse, Fer.
In the revision of the genus Paracaloptenus by Uvarov (1942), two species were recognized: the type-species P. caloptenoides (Brunner v. W., 1861) from southeast Europe, and P. bolivari Uvarov, 1942, from southwest Europe. A third species is described here, P. cristatus sp. n. from northwest Yugoslavia. In P. caloptenoides three subspecies are distinguished: the nominate form, geographically restricted to southeast Europe except northwest Yugoslavia and the Peloponnese, P. brunneri (Stål, 1876) from west Anatolia, and P. moreanus ssp. n. from the Peloponnese. A key to the species and subspecies is given.

The vegetation of the valley of the rivulet Merkske; an evaluation based on a floristic investigation The valley of the meandering rivulet Merkske (in the province of Noord-Brabant, Netherlands, and the province of Antwerp, Belgium) is menaced with deterioration by the intended canalization of the main part of the rivulet (fig. 1 and 2). A new method is described to evaluate the vegetation of this landscape, based on a floristic inventory of all species of vascular plants in each square kilometre in the investigated area. This method is inspired by the Flora statistics proposed bij VAN DER MAAREL (1971). He classified the Dutch species of vascular plants in 19 sociological-ecological groups and in 9 frequency categories (from 1 = very rare, to 9 = very...

The dioecious species of the genus Blyxa can be divided into 2 groups, those with 6 stamens and those with 9 stamens in the male flowers. The first group is restricted to tropical Africa and needs further study. The second group occurs in Asia and Australia and up to now was considered to consist of 2 very distinct species, Blyxa octandra (Roxb.) Planch, ex Thw., characterized by a basal rosette of long, smooth, linear leaves, and B. novoguineensis den Hartog which is caulescent with short serrulate leaves. B. octandra is widely distributed in India, Burma, Indo-China, New Guinea, and the tropical part of Australia. B. novoguineensis is known with certainty only from New Guinea.

Autores: Humes, A.G.
In his original description of the worm Lamellibrachia barhami, found in a depth of 1125 m in the northeastern Pacific, Webb (1969: 31) mentioned "as yet unidentified copepods which live in quite large numbers in interlamellar pockets in the tentacular crown". Webb regarded the worm host as a pogonophoran (Order Vestimentifera), but Dr. J. van der Land of the Rijksmuseum van Natuurlijke Historie, Leiden, believes that the genus Lamellibrachia should be referred to the Annelida, Vestimentifera (in a letter to the author, 13 December 1971). Copepods are not known to be associated with Pogonophora, but many live on polychaete annelids. Through the kindness of Dr. W.

Comparative leaf anatomy of Kokoona and Lophopetalum (Celastraceae)
Provedor de dados: 16
Autores: Jansen, W.T.; Baas, P.
The leaf anatomy of Kokoona and Lophopetalum is described in detail. Separation of the two genera as effectuated by Hou (1963) is supported by differences in vascular anatomy of the distal end of the petiole, which is invariably more complex in Lophopetalum than in Kokoona. Other differential characters (p. ooo) only apply to part of the species of Lophopetalum. As based on leaf anatomy it is impossible to define groups of closely related species within the genera because of a lack of mutual correlation between the different leaf anatomical characters. Lophopetalum in particular shows some striking anatomical features such as a very variable and complex arrangement of vascular tissue in petiole and midrib, complex types of cyclocytic and anisocytic...

Geology of the area between the Luna and Torio rivers, southern Cantabrian Mountains, NW Spain
Provedor de dados: 16
Autores: Staalduinen, C.J. van.
Precambrian clastic rocks, deposited under unstable conditions, were folded before in a relatively stable environment shallow marine sedimentation spread out over the whole area. Silico-clastic sediments were deposited from Cambrian to Devonian, except from the Lower-Middle Cambrian when carbonate deposition dominated. With a hiatus in sedimentation during the Llanvirn to Llandovery the influence of a rising block, NNE of the present area, started. During the Silurian this rise resulted in development of clastic sequences trending to thin towards the N. From the Devonian to Upper Carboniferous sedimentation circumstances became less stable. As a result an alternation of clastic and carbonate rocks developed. Towards the end of the Devonian epeirogenetic...

Isolating mechanisms in fungi—prezygotic, postzygotic, and azygotic
Provedor de dados: 16
Autores: Lemke, Paul A.
What then are the biological processes that influence fungal speciation? Three aspects of fungal biology discussed herein deserved to be reemphasized. First, the great majority of fungi are haploid organisms. Secondly, fungi have expended a considerable amount of genetic energy to control the formation and maintenance of specific heterokaryons. Thirdly, the fungi taken as a group are paradoxical; against a background of extravagant and varied sexual cycles, fungi have a tendency to restrict gene flow and recombination. The prevalence of haploidy, the strict control of heterokaryosis, and an irregular but definite trend toward apomixis are attributes of fungal biology. These phenomena undoubtedly influence the operational details of fungal evolution and...

Excellent scanning electron micrographs of embryonal structures of bispiral Miogypsina's were made, which solve a number of problems raised by details seen in thin sections. Special attention has been paid to the stolon-system near the second primary auxiliary chamber (ΡΑ-II). From the deuteroconch to the ΡΑ-II two funnel-shaped stolons cross the cylindrical protoconchal stolon on both sides. Once a 'lip' around the protoconchal stolon was discovered, it turned out to exist in nearly all the bispiral specimens.

Die Hydroiden der Ciénaga Grande de Santa Marta (Kolumbien) und einiges zu ihrer Ökologie
Provedor de dados: 20
Autores: Wedler, E.
En la Ciénaga Grande de Santa Marta viven dos especies de hidróides estuáricas: Calyptospadix cerula Clarke, 1882 y Cordylophora caspia Pallas, 1771. C. caspia, encontrada hasta ahora solo en el canal frente a los Cocos, está completamente desarrollada en salinidades de 0 a 10°/o/o. C. cerula es eurihalina y existe en salinidades de aprox. 3°/o/o hasta valores completamente marinos. Si la salinidad es inferior a 3°/o/o, esta especie pasa a la fase de menontes. El cambio de actividad de ambas especies depende de la salinidad y probablemente también de la temperatura. En C. caspia, la madurez coincide con el período de agua dulce, mientras C. cerula tiene gonóforos desde comienzos de junio hasta fines de septiembre. Si la salinidad en la Ciénaga Grande es...

Pleistozäne und rezente Mollusken von San Andrés (Karibisches Meer, Kolumbien) mit Bemerkungen zur geologischen Entwicklung der Insel
Provedor de dados: 20
Autores: Geister, J.
Colecciones realizadas en los complejos arrecifales pleistoceno y reciente de la Isla de San Andrés rindieron 38 especies pleistocenas y 121 especies recientes de moluscos marinos. En la distribución ecológica de las especies recientes están representados los biótopos costa rocosa , corales, arena, mangle, terrazas submarinas rocosas y agua profunda. Los hallazgos pleistocenos se restringen a los biótopos costa rocosa, coral y arena. El menor número de especies en la fauna pleistocena se explica parcialmente por la falta de los otros biótopos, pero en primer lugar por la ausencia de las formas de agua poco profunda. Colecciones cuantitativas en los biótopos de arena pleistoceno y reciente , muestran una composición faunística bastante diversa, lo que...

El régimen fluviométrico del Río Magdalena y su importancia para la Ciénaga Grande de Santa Marta
Provedor de dados: 20
Autores: Kaufmann, R.; Hevert, F.
Datos fluviométricos del Bajo Magdalena, sobre largo plazo muestran un ritmo de 6 a 7 años para crecidas y bajas extremas. Con métodos estadísticos (T-test según Student) estos cambios en los niveles resultaron altamente significantes, como también su correlación con variaciones de las precipitaciones en la hoya hidrográfica del Río Magdalena. Las crecidas cíclicas causan inundaciones catastróficas de la Ciénaga Grande de Santa Marta y en consecuencia la desaparición de la ostra Crassostrea rhizophorae, que tiene considerable importancia económica.

An investigation of the pre-lagoonal Holocene sediments beneath the lagoon Cienaga Grande de Santa Marta (Colombia), was undertaken for the purpose of this region before the formation of the lagoon proper. Core and grab samples were collected from the lagoon for stratigraphic observatiion and analysis in the laboratory.  Beneath the recent lagoonal sediments a deposits of peat with intercalated sand and clay was discovered. Its surface lies at a depth of about 2 m below the hydrographic zero level of the lagoon. Three peat samples, obtain from the upper portion of this deposits, were subjected to micropetrographic and pollen analyses. These analyses reveled that, prior to marine inundation, this region in southern Florida (U.S.A.) Sample "f", taken closest...

A new Antarctic lysianassid amphipod, Orchomene hureaui sp.n. from Addlie Land is described and illustrated. The male is unknown. The 2 females were from the stomach of an Adelie penguin. Its epistome is straight and is just in front of the upper lip. The lateral cephalic lobes are rounded and eyes are present. Coxa I is trapezoidal and wide distally, the carpus of gnathopod I shorter than propodite and with no postero-distal lobe, the palm is transverse, slightly convex and deeply toothed. Gnathopod II is subchelate and coxa V has subequal inferior lobes. Uropod III has long setose branches and the telson is divided. The ecology and relations with other Orchomene spp are discussed.

Autores: Daro, M.H.; Polk, P.
The life-history of &lt;i&gt;Polydora ciliata&lt;/i&gt; has been studied in the Bassin de Chasse, Ostende. Three or even four generations succeed one another during the period from April to September. Their planktonic larvae can be found throughout the year, they have a life of 12 to 14 days. Larvae from 3 to 9 segments are growing 2 segments a day, larvae from 10 to 16 segments 1 segment a day. During the first period they feed on nannoplankton or detrital particles, during the second period they are carnivorous, but also detritiphagous and phytophagous. After 3 weeks of sedentary life egg-laying takes place. When one or two broods have been produced most animals die. The eggs hatch after 1 week. The worms are detritiphagous and scrape the food directly...

Growth and toxicity tests on the marine nanoplanktonic alga &lt;i&gt;Platymonas tetrathele&lt;/i&gt; G.S. West in the presence of crude oil and emulsifiers
Provedor de dados: 27
Autores: Mommaerts-Billiet, F.
Phytoplankton response to environmental pollution by oil and emulsifiers has been studied. The nanoplanktonic flagellate &lt;i&gt;Platymonas tetrathele&lt;/i&gt; has been assayed with increasing concentrations of crude oil, industrial non-ionic emulsifiers and mixtures of these products. Cultures poisoned with an emulsifier with an aromatic solvent exhibited a very long lag phase. Diminished growth rates were observed for all the products tested most of the time at concentrations above 50 ppm. The mixtures showed a toxicity close to that of the emulsifier component at its concentration in the mixture and lower than that of the crude oil alone. Fine structure modifications have been investigated and the possible ecological effects of such pollution have...

Swimming behaviour patterns in certain benthic harpacticoids (Copepoda)
Provedor de dados: 27
Autores: Hauspie, R.; Polk, Ph.
During an investigation on the fouling of artificial substrata in a brackish-water biotope at Oostende (=Ostend), Belgium, it was found that some harpacticoid species, until now considered benthic, become pelagic at certain times. Also, we observed that these harpacticoids were swimming during certain periods and then were found in the plankton. Some observations about this phenomenon are discussed in this paper.

A comparison of fast destruction methods for the determination of trace metals in biological materials
Provedor de dados: 27
Autores: Luyten, S.; Smeyers-Verbeke, J.; Massart, D.L.
In clinical chemistry it can be very useful to have a rapid method for the determination of trace elements in biological material available. Because the classical wet digestion method which is generally used for the destruction of biological materials requires much attention, two procedures were tried which should be less time consuming or require less attention. The two new procedures which are the soluene (a quaternary ammonium hydroxide) method of Jackson (1) and the method of Adrian (2) utilizing pressure were applied to the determination of Cu and Zn in human brain tissue and in fish meal by atomic absorption spectroscopy.

Beach samples from the Belgian coast and the Nieuwpoort Channel have been examined for (a) coliform and other common bacteria and (b) more serious pathogens, to determine from their distribution the influence of season, tide, presence of human and other animals and of effluent. There were more coliforms in summer than in spring. State of tides had no significant effect on coliform numbers. The dry sand above HWM, occupied by holidaymakers, was as polluted as intertidal sand. Sand in the Channel near a sewage outfall was rich in coliforms. &lt;i&gt;Salmonella paratyphi &lt;/i&gt; B was also found, but no &lt;i&gt;Shigella&lt;/i&gt; spp., although &lt;i&gt;Shigella phages&lt;/i&gt; were present.

Different metals (Cr, Cu, Fe, Zn, Pb and Ni) were dosed by spectrophotometry of atomic absorption in the North Sea waters and the Scheldt estuary. For some amongst them, a comparison is made between the dosage by spectrophotometry atomic absorption and the measurements by neutron activation. Copper and zinc were dosed in the organisms of three fish common in the North Sea (&lt;i&gt;Pleuronectes platessa&lt;/i&gt;, &lt;i&gt;Gadus merlangus&lt;/i&gt; and &lt;i&gt;Trachurus trachurus&lt;/i&gt;).Its results were put into a report together with its contents and nutrient salts (nitrates, nitrites and phosphates) in the same waters.

The estuary as a habitat: an analysis of data on the soft-bottom macrofauna of the estuarine area of the Rivers Rhine, Meuse, and Scheldt
Provedor de dados: 27
Autores: Wolff, W.J.
During the years 1968-1970 a study has been made of the soft-bottom macrofauna (Coelenterata, Mollusca, Echiuroidea, Polychaeta, Archiannelida, Crustacea Malacostraca) of the estuaries of the rivers Rhine, Meuse, and Scheldt in the southwestern part of The Netherlands and of the adjacent part of the North Sea. 1751 samples were taken with 0.1 and 0.2 m² Van Veen grabs; in the intertidal zone several hundreds of samples were dug out, whereas further samples were taken for the analysis of interstitial polychaetes and archiannelids. Of the environmental factors especially salinity, sediment composition, current velocity, water temperature, oxygen saturation, turbidity, water pollution, exposure to waves, and the influence of ice have been investigated....

On primary production in the South Bight of the North Sea
Provedor de dados: 27
Autores: Mommaerts, J.-P.
The area of the North Sea next to the Belgian and Dutch coasts has been surveyed since January 1971. The photosynthetic capacity (potential production) of samples collected at 63 stations and 4 depths has been measured using the &lt;sup&gt;14&lt;/sup&gt;C techniques. The homogeneity of the water column was demonstrated almost everywhere. A general pattern of decrease of the potential production from the coast to the open sea was demonstrated in all seasons. Figures ranged from 3 to 30 mg C m&lt;sup&gt;-3&lt;/sup&gt; h&lt;sup&gt;-1&lt;/sup&gt;. Primary production was also determined both by calculations, using the Steemann Nielsen (1952) formula, and by &lt;i&gt;in situ&lt;/i&gt; measurements. The higher turbidity near the coast has proved to limit...

Study of trace elements in stratified waters of the Tyrrhenian sea from the surface to 1.000 meters depth
Provedor de dados: 27
Autores: Peeters, E.
During the last 10 years, the Sub-Committee on Oceanic Research of NATO has realized many expiditions in the Tyrrhenian sea and has allowed us to study its hydrology, surface currents, bathymetry and gravimetry. By its topography and characteristics (especially by its deep waters of very long residence time) we have identified it to a close basin. Indeed there are not any important coming waters from the rivers, and the surface currents let us see waters coming out between Sicily and France and in the Strait of Messina; in the other hand two parallele volcanic ridges, one of them being submarine, give an important amount of elements and oligo-elements. We are studying trace elements in stratified waters from the surface to 1.000 meters depth and we hope of...

On the distribution of &lt;i&gt;Eurytemora affinis&lt;/i&gt;(Poppe) (Copepoda) in the Western Scheldt estuary
Provedor de dados: 27
Autores: De Pauw, N.
In the Scheldt estuary, &lt;i&gt;E. affinis&lt;/i&gt; appeared place-bound, dependent on a direct import from quiet breeding-places in connection with the main stream as in the case of mud-flat-saltmarch systems and on an indirect import as in the case of harbours and sluice-docks. This import explains the place-bound presence in different geographically separated places along the axis of the estuary and its presence at different chlorinities, varying between sea and freshwater (17.9-0.071 promille Cl&lt;sup&gt;-&lt;/sup&gt;). The stream itself did not appear to have its "own" autochthonous population. The facts tend to prove that besides physical characteristics of the system, such as the estuarine circulation and the salinity-distribution, the...

The relative importance of nannoplankton in the North Sea primary production
Provedor de dados: 27
Autores: Mommaerts, J.-P.
The South Bight of the North Sea has been investigated for the photosynthetic capacity of net- and nannoplankton, the fractional filtration method being used simultaneously with the C14 technique. The water appeared to be well mixed so that no important variations occurred along the vertical profile. The horizontal distribution of net-/nannoplankton ratios showed, however, a zonation pattern with netplankton-dominant activity near to the coast and nannoplankton-dominant activity further off. The interference of the River Scheldt has also been demonstrated. The various implications of the 'metabolic structure' of the phytoplankton community demonstrated by the fractionation method are discussed.

The consequences of carryover for the optimal application of fertilizer are considered using dynamic programming. The conclusions are relevant for the further problem of deciding how many grain crops to harvest from grain sorghum plants grown in a tropical environment. Dynamic programming is also used for solving this problem for the Ord River Valley, and takes account of the interrelations between season and crop cycle number. Data were obtained from investigations conducted in the area.

RANDOM THOUGHTS ON SOME PROBLEMS OF PROFESSIONAL COMMUNICATION
Provedor de dados: 31
Autores: Burns,   E.O.
Within the profession of agricultural economics are found academics, government economists, farm organization economists, and others. Although the profession is based on general acceptance of principles and judgements, the outlook and activities of an individual are conditioned by his occupational status. Employment affiliations give rise to certain restraints and strains to communication between functional groups. The paper examines this problem, and presents a case for better understanding between the major institutional groups.

A NOTE ON LOSSES FROM PRICE STABILIZATION
Provedor de dados: 31
Autores: Chapman,   R.; Foley,   K.
In a recent article in this journal, Tisdell (1) has taken up the question of price stabilisation as it affects both the growers and users of a raw material, in this case wool. He has constructed a model which purports to show conditions under which a reduction in the variability of wool prices by the operation of a self balancing buffer stock scheme will reduce (a) the producer surplus of growers and (b) the average (or expected) profits of processors.1 While applauding this integrated approach to the problem of commodity price stabilisation, we hold serious reservations about the relevance of Tisdell's conclusions. These suffer from a mistaken inference drawn by Tisdell concerning the effects of a stable versus unstable price regime on the expected total...

Some Estimates of Supply and Inventory Response Functions for the Cattle and Sheep Sector of New South Wales
Provedor de dados: 31
Autores: Freebairn,   John W.
Econometric procedures are employed in an analysis of N.S.W. cattle and sheep producers' decision-making regarding the annual supplies of beef, veal, lamb, mutton and wool, and annual changes in the inventory levels of beef cows, dairy cows, steers, adult sheep and ewes mated to British breed rams. A simultaneous equation model containing fourteen stochastic equations is specified and estimated using annual data for the period 1953-4 to 1970-1. A set of derived reduced form functions are employed in a study of some dynamic behavioural relationships in the cattle and sheep sector. The estimated model is used to analyse some effects on prices, quantities and inventory levels of the imposition of a (10 cent per kg) tax on beef exports.

ECONOMICS OF SIZE IN AUSTRALIAN FARMING
Provedor de dados: 31
Autores: Anderson,   Jock R.; Powell,   Roy A.
Economics of size is an important but relatively neglected aspect of Australian agriculture. The theory and methodology for analysis of economics of size are summarized and a survey made of evidence for Australian agricultural industries. The conclusion is reached that economies of size exist, particularly for small to medium farms and diseconomies appear to be absent. Further research is needed and some important areas are indicated.

SOURCES OF CAPITAL FOR LIMITED RESOURCE COOPERATIVES
Provedor de dados: 31
Autores: Holmquist,   Garth.
Cooperative group actions are undergoing a resurgence in popularity in close concert with an increasing awareness of the problems of rural poverty and a belief that group actions can serve as a partial solution to those problems.  There are several elements necessary for the economic success of a cooperative, of which the absence of any one may preclude economic success and thus greatly diminish or eliminate the usefulness of cooperatives as an anti-poverty tool.  This paper examines capital resources as one prerequisite for economic success by reviewing capital needs and capital sources.  The availability of capital as well as the comparative advantages and disadvantages of the various sources are examined as they apply to limited resource cooperatives....

Finland, in spite of her small size, has developed rather diversified trade relationships with the industrialized countries.  The main trade flows are to the European Economic Community (EEC), the European Free Trade Association (EFTA) and to the Socialist countries in East Europe.  Finland became an associate member of EFTA in July 1961 and in October 1973, after the expansion of EEC with England, Denmark and Ireland, negotiated specials trade arrangements with the EEC to secure her future trade relations.  This arrangement is mainly for forest-based industries and agricultural exports and to avoid the tariff increases on exports from England and West Germany.  With the Socialist countries, the trade is based on bilateral agreements which define the...

ECONOMIC THEORY AND SHEEP-CATTLE COMBINATIONS
Provedor de dados: 31
Autores: Wills,   Ian R.; Lloyd,   Alan G.
This paper deals with the problem of determining the optimum combination of sheep and beef cattle on grazing properties. A major difficulty is that iso-cost functions (production possibility curves) for sheep and cattle are unstable and difficult to estimate because of sheep-cattle-pasture interaction. After discussion of theoretical difficulties consideration is given to practical approaches, based on the iso-cost function concept, which might provide graziers with useful guide-lines. Evidence is presented which suggests that the substitution rate between sheep and cattle with respect to pasture is not constant, and probably varies with stocking rate.

THE VALUE OF INFORMATION PROVIDED BY A UNIFORM GRADING SYSTEM
Provedor de dados: 31
Autores: Freebairn,   John W.
The potential effects of a uniform meat grading scheme on market performance are evaluated in terms of a change in the information state. A uniform grading system may reduce the per unit costs involved in the collection and transmission of information on the characteristics of, and the price differentials for, different units of the commodity set. Under conditions of uncertainty an improved information state will increase market participants' expected utility. A general procedure for an empirical evaluation of a grading scheme is outlined.

The purpose of this paper is to show how the allocation of research resources among commodities and the effects of such allocations on the output mix depend upon (a) the initial production conditions, (b) the nature of the research production functions, and (c) the nature of the demand relations for the commodity outputs. The basic model used is a two-factor, two-product model in which certain types of technical change are introduced.

FORECASTING THE FUTURE FOR TIMBER
Provedor de dados: 31
Autores: Ferguson,   Ian S.
For each State a simple two-equation model of demand and supply was fitted to post-war data using two-stage least squares. Prior estimates of the housing coefficient were used to break collinearity problems in the demand function. Price elasticity of demand appears to be high and income elasticity moderate but declining with increasing income. The use of these estimates in forecasting is briefly outlined.

INTEGRATED RURAL DEVELOPMENT IN AFRICA:  PLANNING AND EVALUATION
Provedor de dados: 31
Autores: Dejene,   Tekola.
In most LDC's, as high as 85 percent of the population is engaged in subsistence agriculture and as high as 90 percent of the population live in the rural sector which comprises the population engaged both in farm and nonfarm activities.  The level of income of the rural population is very low compared to the small urban sector of these countries and the income per capita growth rate is excruciatingly slow.  At the same time this sector contributes 50-60 percent of the GDP in most countries with an average growth rate of 2.5 to 3 percent.  Economists estimate that with population growing at 2 to 3 percent per annum and per capita income consumption rising at 1 percent, there will be an annual increase of 4 percent in demand for food.  This growth in food...

ASSESSMENTS OF THE RELATIVE VALUES OF COMPOUND NITROGEN-PHOSPHORUS FERTILIZERS FOR WHEAT PRODUCTION
Provedor de dados: 31
Autores: Colwell,   J.D.
A general procedure is developed for calculating optimal rates of application of compound fertilizers, containing several nutrients in fixed composition. The calculations are based on response surface models that have been obtained with single nutrient fertilizers. The relative values of alternative compounds can be assessed from the increases in profit that result from their use at optimal rates and this is preferable to simply comparing fertilizer compositions with that of an ideal mix of single nutrient fertilizers. The relative values of a range of standard nitrogen-phosphorus fertilizers are assessed for wheat production in southern New South Wales. The results indicate the need for a compound with a low nitrogen/phosphorus ratio of about 0.5. For the...

AN EMPIRICAL INVESTIGATION OF THE HARVEST OPERATION USING SYSTEMS SIMULATION
Provedor de dados: 31
Autores: Ryan,   Timothy J.
A simple model of the cereal harvest operation was constructed for the Wimmera region of Victoria. The model was used to investigate factors influential in determining the harvesting costs of a machinery system over a period of years. An evaluation of alternative machinery systems was also conducted using the model. The superiority of systems simulation over static analysis was demonstrated by using the model to incorporate stochastic variables and to handle the dynamic nature of the harvest operation. In addition, the model output was shown to provide more information for decision makers than had resulted from previous Australian studies. It was concluded that systems simulation is an appropriate technique for investigating farm management machinery...

The Economics of Agricultural Marketing: A Survey
Provedor de dados: 31
Autores: Breimyer,   Harold F.
Three distinctive schools present diverse interpretations of agricultural marketing. One of these derives from the economics of the farm business and casts marketing as all that happens to products past the farm. A second centres on marketing's co-ordinative role. A third is in allegiance to market development. Contemporary problems, beginning with those of the 1920 price reductions in the United States and accentuated by the worldwide depression of the 1930's, primarily explain the periods of heightened interest in marketing. In the early 1970's the common thread is institutional change in marketing, which originates in events as diverse as declining importance of assembly markets for price discovery, and the redesign of marketing within trading blocs...

The Influence of Financial Factors on Household Meat Consumption Patterns
Provedor de dados: 31
Autores: McShane,   R.W.
In order to assist in the specification of the demand function for Australian meats a sample of housewives was interviewed in an attempt to ascertain how the financial position of a household influences its meat consumption pattern. The three most interesting findings are indicated below. (a) Except for a small proportion of low income households, financial considerations do not play a significant part in determining the quantity of meat purchased but do influence the meat types and cuts that are selected to satisfy the required quantity. (b) It is the "permanent" or "normal" income level of the household which is the dominant financial component influencing its expenditure on meats. (c) It appears that a desire for diet variation, together with the...

The Relationship Between the Price of Wool and the Relative Profitability of Sheep and Cattle Grazing in Australia and its Possible Effect on the Future Supplies of Wool and Beef
Provedor de dados: 31
Autores: Davidson,   Bruce Robinson.
An estimate of the long term elasticity of supply for Australian wool has been made by establishing the price of wool at which 457 farms in the BAE Sheep Industry Survey (1964-5 to 1965-6) would find beef production more profitable than producing sheep and wool. The calculation suggests that the long term elasticity of supply would be of the order of 1'7 to 2'5 depending on the year on which the calculation is based.  The elasticities established in this way were used to estimate the long term supply of Australian wool assuming that the wool industry was exposed to prices similar to those prevailing in 1969-71 over a long period of time.  If future wool prices are of the order of 35 to 40 cents per Ib, Australian wool production might decline by between 35...

Some Implications of Rice Price and Policy Changes for Irrigated Farms
Provedor de dados: 31
Autores: Ryan,   James G.
Parametric linear programming is used to determine the effect of various rice prices combined with the relaxation of acreage controls on the economic viability of the rice enterprise on farms in the irrigation areas of southwestern New South Wales. The relative effects of alternative rice marketing and production policies on the distribution of net incomes among farm size groups is also examined. On 300, 500, and 1,000 acre farms it was found that the price of rice could fall to $25 per long paddy ton before rice is deleted from optimum programmes. Farms in excess of about 400 acres would have had higher percentage net returns to capital and management if acreage controls were eliminated and rice was priced at "free" market levels in the period 1964-68...

Certainty Equivalence and Bias in the Management of Production
Provedor de dados: 31
Autores: Tisdell,   Clement A.
The study uses Theil's concept of certainty equivalence and bias to analyse the production decisions of the purely competitive firm when some of its inputs are controlled and others are non-controlled and subject to random influences. Conditions are outlined under which a surrogate procedure based upon the expected values of the non-controlled variables leads to certainty equivalence and others under which it leads to bias in the controlled variables. General factors which determine the direction of the bias are discussed. The managerial optimality of the surrogate procedure is investigated and also its welfare implications. The analysis is of particular relevance to agriculture because of the prevalence there of random noncontrolled inputs in production.

A perceptible technological transformation has been under way in India during the last few years. The output of total foodgrains increased sharply between 1967-68 and 1970-71 over previous years. There is enough evidence to show that the technological change has resulted in an upward shift in production functions for major crops, especially for wheat.

Natural Waters in Amazonia. VI-Soluble Calcium Properties ()
Provedor de dados: 36
Autores: Brinkmann,W. L. F.; Santos,A. dos.
Abstract The principle sources of the calcium found in the water of the tertiary Amazonian region near Manaus, are the water running over the tree trunks and the total forest water. The soluble calcium content must come from the rain washing the tree crowns, stems, and leaves, and to a certain point from the dissolution of metabolic products of macro and micro-organisms. Generally, only traces of calcium are found in rain water, soil, and river water. Therefore, calcium can be considered as an element circulating in a closed system. Altogether the calcium content in the natural water of the tertiary Amazon region is extremely low.

An evolutionary and ecological perspective of Amazonian Hylaea species of Hymeneae (Leguminosae: Caesalpinioideae)
Provedor de dados: 36
Autores: Langenheim,Jean H.; Lee,Yin-Tse; Martin,Susan S.
Abstract The resin-producing genus Hymenaea has an amphi-Atlantic distribution with 13 species being Neotropical and one occurring along the eastern coast of Africa. Present evidence suggests an African origin for the genus with migration across the Atlantic occurring during the Early Tertiary when the continents were closer and rainforest vegetation was considerably more widely distributed than today. The center of its Neotropical distribution is the Amazonian hylaea, although within its extensive range from 23° N to 26° S it is found in all major ecosystem types. The taxonomy, breeding structure, ecology and resin chemistry of the 9 Hymenaea species and 6 varieties occurring in the Amazonian and historically-related Brazilian Atlantic coastal humid...

Abstract This paper makes use of energy flow language. It discusses how this energetics approach can be useful in research having to do with the interactions between man and the environment. All life processes have energy as their common denominator. The paper shows how this methodological approach aids in field preparation, organizes research while in the field and helps in the analysis of data. A discussion of manioc as an essential plant for man in the tropics is presented, and the myths surrounding the plant are indicated and recent research finds put in context. The potential of manioc as a food of the future is presented and suggestions are made for an energetics approach to the plant in situ. The plant's potential needs to be studied in the context...

The effect of slash and burn agriculture on plant nutrients in the Tertiary Region of Central Amazonia ()
Provedor de dados: 36
Autores: Brinkmann,W. L. F.; Nascimento,J. C. do.
SUMMARY The slash and burn method was studied with respect to changes on the chemical composition in the top-soil layer (upper 20 cm) of yellow latosols (about 85% of the total area) and hydromorphic soils (about 1% of the total area) before and after fire was set on the cleared forest. The obtained analytical data prove the following result : 1) the soil fertility of latosols and hydromorphic soils is considerably low as far as natural conditions are concerned, 2) after burning a considerable amount of plant nutrients normally bound to the standing crop is lost in the form of volatiles and particles during the burning procedures, 3) a great amount of plant nutrients is rapidly released to the soil after burning, 4) great quantities of temporarily...

Phytogeographic support tor the theory of Pleistocene forest refuges in the Amazon Basin, based on evidence from distribution patterns in Caryocaraceae, Chrysobalanaceae, Dichapetalaceae and Lecythidaceae
Provedor de dados: 36
Autores: Prance,Ghillean T.
Abstract In recent years it has generally been accepted that Amazonia was subject to long dry periods in the late Pleistocene and post-Pleistocene which induced forest cover to a few limited areas or refuges. It has been proposed that the subsequent genetic isolation into separate populations is a mnjor factor in the evolution of the species diversity within the lowland forest of Amazonia. Most of the previous evidence for this theory is based on studies of animals, for example: lizards, butterflies, and birds. Here data are presented to confirm the theory of forest refuges using evidence from phytogeography. Distribution patterns of the lowland species of the woody plant families Caryocaraceae, Chrysobalanaceae, Dichapetalaceae and Lecythidaceae are...

Autores: Moraes,Mário Augusto Pinto de.
Sinopse De 696 casos de micoses superficiais, encontrados em Manaus — Estado do Amazonas, durante um período de 7 anos (1961 - 1968), isolaram-se 515 amostras de fungos, das quais 440 pertenciam a espécies do grupo dos dermatófitos. O fungo predominante foi Trichophyton tonsurans, responsável por 282 das 440 amostras, ou seja, 64% do total de dermatófitos. Contribuiu para este percentual, bastante elevado, o fato de ser T. tonsurans quase que o único agente causador de tinha da cabeça nas crianças de Manaus: em 242 casos de tinha tonsurante apareceu ele 234 vezes, e em 30 casos de quério, 23 vezes. Nas pessoas maiores de 15 anos, todavia, o dermatófito mais encontrado foi T. mentagrophytes; apareceu ele 106 vezes, contra apenas 16 de T. tonsurans, em 145...

O método micro Bailey-Andrew, oficial da A. O. A, C. (1970) e o proposto por NAVELLIER et al. (1969) para determinação de cafeína em café, foram comparados. Para extração e purificação seguiu-se os dois métodos citados e para a determinação propriamente dita utilizou-se o peso, nitrogênio total, espectrofotometria com correção da linha de base e o pico à 273 nm. As seguintes conclusões foram tiradas: a) A determinação por pesagem não deve ser utilizada para nenhum dos dois métodos de extração e purificação, pois além dos valores encontrados serem bem acima dos reais, os coeficientes de variação também foram altos. b) O método de extração e purificação de NAVELLIER et al.

Três métodos de determinação do ácido clorogênico em café verde foram comparados. Foram utilizadas seis amostras de café, sendo que três de qualidade de bebida Mole e três Rio. Os resultados obtidos com os três métodos para os cafés Rio não diferiram estatísticamente entre si, embora os métodos de MOORES et al. e WEISS (oficial da AOAC) deram valores menores para os cafés Mole em relação ao método cromatográfico de GNAGY modificado. É discutido uma provável interferência da alta atividade da polifenol oxidase geralmente encontrada nos cafés Mole que oxidaria o ácido clorogênico durante a extração pelos dois primeiros métodos.

Provedor de dados: 43
Autores: Amorim,H. V.; Teixeira,A. A.; Moraes,R. S.; Reis,A. J.; Gomes,F. Pimentel; Malavolta,E.
O efeito da adubação N, P e K na composição mineral do grão (macro nutrientes, B e Zn) e na qualidade da bebida (prova de xícara) foi estudado. Utilizou-se um ensaio de adubação NPK, 3x3x3 plantado em 1955 em Ribeirão Preto, S. P. As amostras foram colhidas a dedo, despolpadas e degomadas no mesmo dia. Verificou-se que somente a adubação nitrogenada aumentou significativamente o teor de N no grão. Altos niveis de K na adubação diminuíram o teor de B e de Zn no grão. O teor de N no grão foi correlacionado negativamente com a qualidade da bebida. A adubação potássica quando excessiva prejudicou a qualidade da bebida mas de uma maneira não consistente. O aumento da produção causado pela adubação nitrogenada e potássica compensam economicamente o pequeno...

Influência de alguns métodos de controle do escurecimento enzimático nas propriedades organoléticas da maçã Bruckner do Brasil conservada por congelação e liofilização
Provedor de dados: 43
Autores: Nogueira,João Nunes.
No presente trabalho foi estudada a influência de três métodos de controle do escurecimento enzimático (branqueamento, ácido ascórbico e SO2) nas propriedades organoléticas da maçã em pedaços da variedade Bruckner do Brasil, conservada por congelação e liofilização. Imediatamente após seu recebimento, uma terça parte das frutas foi processada. Outra terça parte foi colocada em câmara fria a 1°C por três semanas e a restante deixada sob as mesmas condições por seis semanas, sendo estas duas últimas processadas imediatamente após os respectivos tempos de armazenamento prévio. Para a congelação, o branqueamento foi considerado o melhor tratamento para todos os atributos de qualidade, exceto para cor, em que o SO2 e o ácido ascórbico foram superiores. Em...

Autores: Sarruge,José R.; Biasi,José; Castro,Paulo R. C.; Defelipo,Braz V.; Feitosa,Celi; Krug,Francisco J.; Morelli,Maurelio.
No trabalho apresentado, estudou-se a cinética de absorção de íons, baseado na equação de LINEWEAVER &amp;amp; bURk (1934). o estudo visou verificar o efeito competitivo ou não do íon Mg²+ na absorção do íon Ca²+. Para facilidade do estudo, soluções de CaCl2 marcadas com 45Ca foram administradas em diferentes concentrações à tecidos foliares de café (Coffea arabica L., cv. 'Mundo Novo'), em solução contendo ou não uma concentração conhecida de MgCl2 segundo a técnica de SMITH &amp;amp; EPSTEIN (1964a e 1964b). São apresentados também cálculos estatísticos, considerados inéditos na aplicação do presente estudo. Conclue-se que há inibição competitiva devida ao íon Mg²+ pelos centros ativos dos carregadores.

Provedor de dados: 43
Autores: Servin,Geraldo Moreno; Mello,Francisco de A. F. de; Moraes,Roberto S.
Ê descrito um ensaio de incubação com a finalidade de estudar os efeitos da adição de CaCO3 sobre o pH e Al³+ e H+ trocáveis de 4 terras, servindo-se do método do Al³+ trocàvel para a determinação das doses de CaCO3. De um modo geral, se encontrou uma forte elevação nos índices pH das terras e redução nos teores de Al³+ e de H+ trocáveis das mesmas, à medida em que se aumentavam as quantidades de CaCO3 empregadas. A dose 1 de CaCO3, que correspondia à quantidade de cálcio estequiometricamente igual à de Al³+ trocável presente em cada terra, foi suficiente para elevar o pH de todas elas ao redor de 5,7. O teor de Al³+ trocável, contudo, em uma delas permaneceu acima do nível considerado não tóxico às plantas.

Sílica solúvel em solos
Provedor de dados: 53
Autores: Raij,Bernardo van; Camargo,Otávio Antônio de.
Determinou-se a silica solúvel nos horizontes superficial e B2 de 44 perfis de solos do Estado de São Paulo. A extração da silica com solução 0,0025M de cloreto de cálcio evitou a dispersão dos solos e forneceu resultados em média apenas 8% menores do que a silica solúvel em água. Os resultados variaram de 2,2 a 92,2 ppm de SiO2. Verificou-se que, para solos com teores semelhantes de argila, os teores de silica solúvel foram maiores para solos com horizonte B textural, quando comparados com solos de horizonte B latossólico. Dentro dos agrupamentos de solos com horizonte B textural e horizonte B latossólico, os teores de silica solúvel foram maiores para os solos mais argilosos. Não foi observada relação entre silica solúvel e o pH dos solos.

Efeito residual de fosfatos sobre o desenvolvimento e a produção do algodoeiro cultivado em solo podzólico vermelho-amarelo orto
Provedor de dados: 53
Autores: Silva,Nélson M. da; Ferraz,Carlos A. M.; Cia,Edivaldo; Sabino,Nelson P.; Cruz,Luciano S. P.
O efeito residual de adubação fosfatada, fornecida por superfosfato simples à variedade paulista de algodoeiro IAC 12-2, foi comparado àquele devido aos termofosfatos Foscal, Foscadu e Fosleucal em. solo Podzólico Vermelho-Amarelo orto, do Estado de São Paulo, durante três anos. No primeiro ano de efeito residual da adubação, o superfosfato simples influenciou favoravelmente a produção e a precocidade das plantas. Tal efeito foi proporcional à dose de adubo utilizada no ano base. A partir do segundo ano, decresceu gradativamente o efeito residual do produto. Os termofosfatos não se igualaram ao superfosfato em efeito residual de primeiro ano. Foscal e Foscadu aproximaram-se mais do superfosfato, a partir do segundo ano. Entretanto, os efeitos dos...

Determinação do ponto de carga zero em solos
Provedor de dados: 53
Autores: Raij,Bernardo van.
São apresentados os fundamentos e dois métodos de determinação do ponto de carga zero (PCZ) em solos. Por um dos métodos o PCZ foi determinado como sendo o pH do ponto de cruzamento de curvas de titulação dos solos em soluções de NaCl 1; 0.1; 0 01; c 0,001N. Pelo outro método o PCZ foi determinado por extrapolação ou interpolação da carga líquida dos solos, determinada por retenção de íons em soluções de NaCl 0,2N, CaCl2 0,01N e MgSO4 0,01N, ao valor de pH em que a carga líquida era nula.

Determinação de cargas elétricas em solos
Provedor de dados: 53
Autores: Raij,Bernardo van.
As cargas elétricas dos solos estudados variaram em função da concentração da solução, do pH e da valência dos íons trocáveis. Optou-se pela determinação das cargas em condições de equilíbrio relativamente a pH e concentração da solução, omitindo-se uma lavagem total do excesso de solução salina. Cargas positivas e negativas variaram com o sal empregado, para amostras do horizonte B2 de um Latossolo Roxo e de uma Terra Roxa Estruturada, aumentando na ordem NaCl&lt;CaCl2&lt;MgS0(4), para determinados valores de concentração e pH.

Influência dos óxidos de ferro livres e da matéria orgânica na adsorção da água pelo solo
Provedor de dados: 53
Autores: Grohmann,Francisco; Camargo,Otávio Antônio de.
Foi estudada a correlação entre a superfície específica e a água higroscópica de quatro perfis de latossolos e cinco perfis de podzólicos, num total de 42 amostras. Estudou-se, também, a influência da matéria orgânica do solo e dos óxidos de ferro livres na retenção da água. Foram encontrados coeficientes de correlação bastante elevados entre superfície específica e água higroscópica, para os diversos tratamentos a que foram submetidas as amostras. Os óxidos de ferro livres, de uma maneira geral, aumentam o teor de água retida nas condições estudadas, enquanto a presença da matéria orgânica prejudica a adsorção da água.

Autores: Gridi-Papp,Imre L.; Cia,Edivaldo; Ferraz,Carlos A. M.; Cavaleri,Popílio A.; Fuzatto,Mílton G.; Silva,Nélson M. da; Sabino,Nélson P.
Um processo contínuo de testes de algodoeiros, em condições naturais de infestação por Fusarrum oxysporum f. vasinfectum (Atk.) Snyder &amp;amp; Hansen, é descrito e discutido. Consiste, basicamente, em ciclos de seleção de três anos. Seleções individuais são feitas no primeiro ano, e as progenies são testadas no segundo. Ainda no segundo ano são realizadas seleções massais nas melhores progênies, e as populações descendentes são estudadas no terceiro ano. A avaliação dos resultados obtidos em dois ciclos consecutivos mostrou que o método foi eficiente, incrementando, em qualquer dos materiais estudados, a tolerância e a resistência à moléstia, expressas em índices apropriados. O progresso foi maior em material suscetível de origem do que em material...

Efeito do tamanho do vaso e da época de corte de plantas de trigo no estudo da ação dos nutrientes N, P e K
Provedor de dados: 53
Autores: Gargantini,Hermano; Soares,Edmir.
Em casa de vegetação, utilizando vasos de barro com capacidade para 0,6, 6 e 10 kg, pesquisou-se a influência das épocas de corte, para estudo da ação do nitrogênio, do fósforo e do potássio, no desenvolvimento e produção do trigo (Triticum aestivum L.). O vaso de maior capacidade serviu de base para as comparações com os de menores volumes. As colheitas foram efetuadas aos 30, 60, 90 e 120 dias (produção de grãos). Foi utilizado um Latossolo Vermelho-Escuro, nos quais empregaram-se os tratamentos: N0P0K0, N0P1K1, N1P0K1. N1P1K0, e N1P1K1. Os dados obtidos permitiram observar que em vasos de 0,6 kg é possível estudar a ação do nitrogênio e do fósforo, colhendo-sc as plantas aos 60 dias. Em vasos de 6 kg pode-se estudar o efeito do fósforo já aos 30 dias...

Efeito de diversos fertilizantes fosfatados na produção de trigo cultivado em vasos
Provedor de dados: 53
Autores: Gargantini,Hermano; Soares,Edmir.
Este trabalho teve como objetivo estudar comparativamente o valor fertilizante de diversos materiais fosfatados, empregando trigo (Triticum aestivum L.) como planta indicadora. Utilizaram-se os seguintes fertilizantes: superfosfato simples, superfosfato triplo, dois tipos de termofosfatos, fosfato de diamônio e um fosfato natural tricálcico. O ensaio foi conduzido em vasos, em casa de vegetação. Os resultados mostraram grande resposta à aplicação dos fosfatos. Entre os fertilizantes estudados, verificou-se que os superfosfatos simples e triplo, fosfato de diamônio e um dos termofosfatos apresentaram as melhores produções, não havendo diferenças entre eles, enquanto um dos termofosfatos e o fosfato natural produziram pequeno efeito.

Provedor de dados: 53
Autores: Scaranari,Hélio José; Martins,Fernando Picarelli; Igue,Toshio.
Em experimento levado a efeito na Estação Experimental de Jundiaí, procurou-se verificar a conveniência ou não de corrigirem-se as falhas de brotação comumente observadas em videira da variedade Niágara Rosada, quando conduzida em espaldeira, no sistema denominado cordão esporonado. Consideraram-se quatro casos: plantas que apresentavam 5, 4, 3 e 2 esporões, as quais foram corrigidas para 6 esporões, número médio observado em videiras adultas, quando o espaçamento entre plantas é de 1 metro. Nos cinco biênios estudados, as produções médias das plantas corrigidas para 6 esporões superaram as das não corrigidas, que apresentavam 5, 4, 3 e 2 esporões, em 12, 26, 60 e 158 por cento, respectivamente.
